6. BRIEF RESUME OF THE INTENDED WORK

Introduction

The concept of "available, accessible and affordable" is central to the successful implementation of any planned program.

A chest drain (chest tube or tube thoracostomy in British medicine or intercostal drain) is a flexible plastic tube that is inserted through the side of the chest into the pleural space. It is used to remove air (pneumothorax) or fluid (pleural effusion, blood, chyle), or pus (empyema) from the intrathoracic space. It is also known as a Bülau drain or an intercostal catheter1.

Before we discuss the chest drainage in detail, it is important to briefly review normal anatomy and physiology of the thorax with emphasis on the physiology of respiration. This will help us understand what can go wrong in the structure and function of the chest and how these problems can be treated. CHEST WALL: The chest wall is made up of bones and muscles. The bones, primarily ribs, sternum and vertebrae, form a protective cage for the internal structures of the thorax. The main muscles of the chest wall, the external and internal intercostals, extend from one rib to the rib below. The external intercostals enlarge the thoracic cavity by drawing the ribs together and elevating the rib cage, while the internal intercostals decrease the dimensions of the thoracic cavity

MEDIASTINUM: Within this musculoskeletal cage of the thorax are three subdivisions. The two lateral subdivisions hold the lungs. Between the lungs is the mediastinum, which contains the heart, the great vessels, parts of the trachea and esophagus, and other structures

LUNGS: The lungs consist of airways (trachea and bronchi) that divide into smaller and smaller branches until they reach the air sacs, called alveoli. The airways conduct air down to the alveoli where gas exchange takes place.

The lung itself is covered with a membrane called the visceral (or pulmonary) pleura. The visceral pleura are adjacent to the lining of the thoracic cavity which is called the parietal pleura. Between the two membranes is a thin, serous fluid which acts as a lubricant – reducing friction as the two membranes slide across one another when the lungs expand and contract with respiration. The surface tension of the pleural fluid also couples the visceral and parietal pleura to one another, thus preventing the lungs from collapsing. Since the potential exists for a space between the two membranes, this area is called the pleural cavity

RESPIRATION: Respiration is a passive, involuntary activity. Air moves in and out of the thorax due to pressure changes. When the diaphragm, the major muscle of respiration, is stimulated, it contracts and moves downward. At the same time, the external intercostals move the rib cage up and out. The chest wall and parietal pleura move out, pulling the visceral pleura and the lung with it. As the volume within the thoracic cavity increases, the pressure within the lung decreases. Intrapulmonary pressure is now lower than atmospheric pressure; thus air flows into the lung inhalation2.

When the diaphragm returns to its normal, relaxed state, the inter-costal muscles also relax and the chest wall moves in. The lungs, with natural elastic recoil, pull inward as well and air flows out of the lungs -exhalation. The lungs should never completely collapse for there is always a small amount of air, called residual volume, in them. Under normal conditions, there is always negative pressure in the pleural cavity. This negative pressure between the two pleurae maintains partial lung expansion by keeping the lung pulled up against the chest wall. The degree of negativity, however, changes during respiration. During inhalation, the pressure is approximately –8 cm H2O; during exhalation, approximately –4 cm H2O. If a patient takes a deeper breath, the intrapleural pressure will be more negative. Under normal conditions, the mechanical attachment of the pleurae, plus the residual volume, keep the lungs from collapsing.

INDICATIONS

• Pneumothorax: accumulation of air in the pleural space

• Pleural effusion: accumulation of fluid in the pleural space

• Chylothorax: a collection of lymphatic fluid in the pleural space

• Empyema: a pyogenic infection of the pleural space

• Hemothorax: accumulation of blood in the pleural space

• Hydrothorax: accumulation of serous fluid in the pleural space

CONTRAINDICATIONS

Contraindications to chest tube placement include refractory coagulopathy, lack of cooperation by the patient, and diaphragmatic hernia. Additional contraindications include scarring in the pleural space (adhesions)

TECHNIQUE

The insertion technique is described in detail in an article of the NEJM. The free end of the tube is usually attached to an underwater seal, below the level of the chest. This allows the air or fluid to escape from the pleural space, and prevents anything returning to the chest. Alternatively, the tube can be attached to a flutter valve. This allows patients with pneumothorax to remain more mobile.

British Thoracic Society recommends the tube is inserted in an area described as the "safe zone", a region bordered by: the lateral border of pectoralis major, a horizontal line inferior to the axilla, the anterior border of latissimus dorsi and a horizontal line superior to the nipple More specifically, the tube is inserted into the 5th intercostal space slightly anterior to the mid axillary line.

Chest tubes are usually inserted under local anesthesia. The skin over the area of insertion is first cleansed with antiseptic solution, such as iodine, before sterile drapes are placed around the area. The local anesthetic is injected into the skin and down to the muscle, and after the area is numb a small incision is made in the skin and a passage made through the skin and muscle into the chest. The tube is placed through this passage. If necessary, patients may be given additional analgesics for the procedure. Once the tube is in place it is sutured to the skin to prevent it falling out and a dressing applied to the area. Once the drain is in place, a chest radiograph will be taken to check the location of the drain. The tube stays in for as long as there is air or fluid to be removed, or risk of air gathering.

Chest tubes can also be placed using a trocar, which is a pointed metallic bar used to guide the tube through the chest wall. This method is less popular due to an increased risk of iatrogenic lung injury. Placement using the Seldinger technique, in which a blunt guidewire is passed through a needle (over which the chest tube is then inserted) has been described.

COMPLICATIONS

Major complications are hemorrhage, infection, and reexpansion pulmonary edema. Chest tube clogging can also be a major complication if it occurs in the setting of bleeding or the production of significant air or fluid. When chest tube clogging occurs in this setting, a patient can suffer from pericardial tamponade, tension pneumothorax, or in the setting of infection, an empyema. All of these can lead to prolonged hospitilization and even death. To minimize potential for clogging, surgeons often employ larger diameter tubes. These large diameter tubes however, contribute significantly to chest tube related pain. Even larger diameter chest tubes can clog. In most cases, the chest tube related pain goes away after the chest tube is removed, however, chronic pain related to chest tube induced scarring of the inter-costal space is not uncommon.

In recent years surgeons have advocated using softer, silicone Blake drains rather than more traditional PVC conventional chest tubes to address the pain issues. Clogging and chest tube occlusion issues have been a problem, including reports of life threatening unrecognized bleeding that occurs in the chest due to an occluded or clogged drain. Thus when a chest tube is inserted for whatever reason, maintaining patency is critical to avoid complications.

Injury to the liver, spleen or diaphragm is possible if the tube is placed inferior to the pleural cavity. Injuries to the thoracic aorta and heart have also been described. Minor complications include a subcutaneous hematoma or seroma, anxiety, shortness of breath (dyspnea), and cough 3.

6.1 NEED FOR THE STUDY

In current hospital practice chest drains are used in many different clinical settings and doctors in most specialties need to be capable of their safe insertion. The emergency insertion of a large bore chest drain for tension pneumothorax following trauma has been well described by the Advanced Trauma and Life Support (ATLS).

It has been shown that physicians trained in the method can safely perform tube thoracostomy with 3% early complications and 8% late. The safe insertion of chest tubes in the controlled circumstances usually encountered by physicians needs training4.

A review of 114 thoracic empyema cases attended in the thoracic unit of the Muhimbili Medical Centre from July 1986 to July 1990 is presented. 87.7% of the cases were males. Their ages ranged from 9 to 79 years with a mean of 32 years. Tuberculosis was the major cause accounting for 63.2% of all the cases. 53.4% of the patients underwent either open chest drainage decortication or thoracoplasty. The duration of hospital stay ranged from 2-8 months with a mode around 3.5 months. A 7% mortality was noted.

Quantifying the frequency of hemothorax in the general population is difficult. A very small hemothorax can be associated with a single rib fracture and may go undetected or require no treatment. Because most major hemothoraces are related to trauma, a rough estimate of their occurrence may be gleaned from trauma statistics. Approximately 150,000 deaths occur from trauma each year. Approximately 3 times this number of individuals are permanently disabled because of trauma, and the majority of this combined group are victims of polytrauma. Chest injuries occur in approximately 60% of polytrauma cases; therefore, a rough estimate of the occurrence of hemothorax related to trauma in the United States approaches 300,000 cases per year.

In a 34-month period at a large level-one trauma center, 2086 children younger than 15 years were admitted with blunt or penetrating trauma; 104 (4.4%) had thoracic trauma. Of the patients with thoracic trauma, 15 had hemopneumothorax (26.7% mortality rate), and 14 had hemothorax (57.1% mortality rate). Many of these patients had other severe extrathoracic injuries. Nontraumatic hemothorax carries a much lower mortality rate.

In another series of children with penetrating chest injuries (ie, stab or gunshot wounds), the morbidity rate was 8.51% (8 of 94). Complications included atelectasis (3), intrathoracic hematoma (3), wound infection (3), pneumonia (2), air leak for more than 5 days (2), and septicemia (1). Note that these statistics apply only to traumatic hemothorax5.Spontaneous pneumothorax is more common in males than in females. The annual incidence of PSP is 18–28 per 100,000 in males and 1.2–6.0 in females. Secondary spontaneous pneumothorax is less common, with 6.3 for males and 2.0 for females. Risk of recurrence depends on underlying lung disease. Once a second episode has occurred, there is a high likelihood of subsequent further episodes. Smokers have an increased risk of contracting a first spontaneous pneumothorax of approximately ninefold among women and 22-fold among men compared to non-smokers. The incidence in children has not been well studied, but it is probably less than that of adults and often reflects underlying lung disease.

Death from pneumothorax is very uncommon (except for tension pneumothorax). British statistics have revealed an annual mortality of 1.26 per million per year in men and 0.62 in women. Mortality is higher in older people and those with secondary pneumothorax.Thoracotomy may be performed to diagnose or treat a variety of conditions; therefore, no data exist as to the overall incidence of the procedure. Lung cancer, a common reason for thoracotomy, is diagnosed in approximately 172,000 people each year and affects more men than women (91,800 diagnoses in men compared to 80,100 in women).

One study following lung cancer patients undergoing thoracotomy found that 10–15% of patients experienced heartbeat irregularities, readmittance to the ICU, or partial or full lung collapse; 5–10% experienced pneumonia or extended use of the ventilator (greater than 48 hours); and up to 5% experienced wound infection, accumulation of pus in the chest cavity, or blood clots in the lung. The mortality rate in the study was 5.8%, with patients dying as a result of the cancer itself or of postoperative complications6.

(American Lung Association, June 2005)

▪ Morbidity: Primary spontaneous pneumothorax affects 9,000 persons per year and is more common in tall, thin men between 20 and 40 years of age.

▪ Recurrence rate: Is about 40% for both primary and secondary spontaneous pneumothorax, occurring in intervals of 1.5 to 2 years.

▪ Mortality: Rate is 15% for those with secondary pneumothorax.

The following statistics relate to the incidence of Pneumothorax:

• 1.011 per 1,000 hospitalized at risk patients developed iatrogenic pneumothorax in America 2000-2002

• 33,571 cases of iatrogenic pneumothorax occurred in the US 2000-2002

• 18.57% of cases of iatrogenic pneumothorax resulted in death in the US 2000-2002

• Incidence rate statistics for Iatrogenic Pneumothorax in the USA:

Estimated 0.738 Iatrogenic pneumothorax occurred per 1,000 hospital discharges (excluding patients with trauma, thoracic surgery, lung or pleural biopsy or cardiac surgery and neonates) of people aged over 65 in the US 2000 (National Healthcare Quality Report, AHRQ, DHHS, 2003)

The following are statistics from various sources about deaths and Pneumothorax:

1. 2,347 deaths from iatrogenic pneumothorax were attributable to a patient safety incident in the US 2000-2002 (Patient Safety in American Hospitals, Health Grades 2004)

2. 6.99% of deaths from iatrogenic pneumothorax were attributable to the patient safety incident in the US 2000-2002 (Patient Safety in American Hospitals, Health Grades 2004)

The following are statistics from various sources about hospitalizations and Pneumothorax:

• 0.07% (9,054) of hospital consultant episodes were for pneumothorax in England 2002-03 (Hospital Episode Statistics, Department of Health, England, 2002-03)

• 73% of hospital consultant episodes for pneumothorax required hospital admission in England 2002-03 (Hospital Episode Statistics, Department of Health, England, 2002-03)

• 72% of hospital consultant episodes for pneumothorax were for men in England 2002-03 (Hospital Episode Statistics, Department of Health, England, 2002-03)

Thoracotomy and pulmonary resection are infrequently required for lung trauma. Tube thoracostomy and supportive measures successfully manage the vast majority of chest traumas. Nursing management of chest drains is important. A comprehensive understanding of the operations of the chest drain systems and areas requiring special attention would be important to reduce the complications arising from chest tube drainage7.

6.2 REVIEW OF LITERATURE

The review of literature is defined as broad, comprehensive in-depth, systematic and critical review of scholarly publications, unpublished scholarly print materials, audio visual materials and personal communications.

Lehwaldt D, Timmins F conducted a study on “Nurses' knowledge of chest drain care: an exploratory descriptive survey” which says that chest drains are a common feature of patients admitted to acute respiratory or cardio-thoracic surgery care areas. Chest drains are either inserted intra-operatively or as part of the conservative management of a respiratory illness or thoracic injury. Anecdotally, there appears to be a lack of consensus among nurses on the major principles of chest drain management. Many decisions tend to be based on personal factors rather than sound clinical evidence. This inconsistency of treatment regimes, together with the lack of evidence-based nursing care, creates a general uncertainty regarding the care of patients with chest drains. This study aimed to identify the nurses' levels of knowledge with regard to chest drain management. The research objective of this study was to describe the nurses' levels of knowledge regarding the care of the patient with chest drains. The data were collected using survey method. The results of the study revealed deficits in knowledge in a select group of nurses. Several service-led options exist with regard to improving knowledge in this area, such as service study days as well as ward-based tutorials. However, in an era of increasing accountability together with the impetus for each nurse to provide evidence-based care, it is crucial for individual nurse responsibility in the pursuit of knowledge in this area. Nurses must be supported by local practice development and through personal portfolio use to identify gaps in knowledge and seek appropriate training and resources8.

Lehwaldt D, Timmins F conducted a study on “The need for nurses to have in service education to provide the best care for clients with chest drains” which says that chest drains are a widespread intervention for patients admitted to acute respiratory or cardiothoracic surgery care areas. These are either inserted intra-operatively or as part of the conservative management of a respiratory illness or thoracic injury. Anecdotally there appears to be a lack of consensus among nurses on the major principles of chest drain management. Many decisions tend to be based on personal factors rather than sound clinical evidence. This inconsistency of treatment regimes, together with the lack of evidence-based nursing care, creates a general uncertainty regarding the care of patients with chest drains. This study aimed to identify the nurses' levels of knowledge with regard to chest drain management and identify and to ascertain how nurses keep informed about the developments related to the care of patients with chest drains. The data were collected using survey method. The results of the study revealed deficits in knowledge in a selected group of nurses and a paucity of resources. Nurse Managers are encouraged to identify educational needs in this area, improve resources and the delivery of in service and web-based education and to encourage nurses to reflect upon their own knowledge deficits through portfolio use and ongoing professional development9.

Elsayed H, Roberts R et al conducted a study on “Chest drain insertion is not a harmless procedure--are we doing it safely?” which says that the incorrect insertion of a chest drain can cause serious harm or even death. All elective drains should be inserted in the 'triangle of safety' in line with the British Thoracic Society guidelines. The aim of this study was to test the awareness of nurses involved in inserting chest drains with these guidelines. Fifty nurses were questioned. Participants were asked to grade their experience of chest drain insertion and mark on a diagram where they felt was the optimum site for inserting a drain for a large pneumothorax in an elective situation. Only 44% (n=22) of nurses indicated they would insert a chest drain within the safe triangle. Level of experience, seniority and specialty all had an effect on knowledge of the correct site. Of those who had inserted drains unsupervised, 48% (n=16) would site the drain outside the safe triangle as would 75% (n=6) of those who had performed the procedure supervised. Only 25% of medics knew where to insert a drain, compared with 58% of nurses working in surgery. The majority of nurses do not have the basic knowledge to insert a chest drain safely. Further training in this procedure is needed for nurses10.

Sim KM, Ng AS conducted a study on “A questionnaire survey on practice of chest tube management” with the aim towards better education of junior medical staff on chest tube management, we designed a questionnaire to survey their practice and at the same time to assess their level of understanding of the physical principles of chest tube and its drainage system.The questionnaire was distributed to 130 junior medical staff (house officers, medical officers, trainee medical officers and specialist medical officers) from 7 Medical and Surgical Departments in Singapore General Hospital. Eighty-seven (66.9%) candidates responded. The mean age of the respondents was 27 +/- 2.1. They had an average of 3.2 +/- 1.9 years after basic medical qualification and 5 hospital postings. Nine respondents had obtained higher medical qualifications.About a quarter of the respondents, and 40% of those with higher medical qualifications gave appropriate answers. Ninety percent indicated that they received no lectures on chest tube management. Incomplete response ranged from 0% to 6%. To improve education on chest tube management, our results and the feedback we obtained from the respondents, suggest that lectures on important physical principles of chest tube and its drainage system should be delivered to all junior medical staff11.

Munnell ER conducted a study on “Thoracic drainage” which says that the evacuation of empyemas first performed centuries ago, marked the beginning of thoracic drainage. The subsequent acquisition of a greater knowledge of the anatomy, physiology, and pathology of the pleural space directed the design of thoracic catheters and drainage systems and the development of the methods by which they are used. Furthermore, a better understanding of the physics of vacuum and air flow brought about improvements in the use of suction with drainage. Today, thoracic catheters, chest drainage systems, and most vacuum sources are well designed and well made and incorporate components needed to achieve the best care of the pleural-mediastinal space. This review covers the development and important considerations in the current use of thoracic drainage. Knowledge of the principles of chest tube drainage is important to evaluate adequately the function of a tube thoracostomy12.

Sullivan B conducted a study on “Nursing management of patients with a chest drain” which says that Chest drains incorporate the use of a one-way valve to drain fluid or air from the pleural cavity. The valve prevents back-flow of air and fluid into the pleural cavity. They are indicated for use when collections of fluid or air are present in the pleural space, and by draining the collection they restore efficient gaseous exchange. Little has been written on the nursing management of chest drains and the literature highlights a lack of national standardized guidelines for due to the range of thoracic conditions encountered by clinical staff. Themes such as pain management and mechanism of breathing occur frequently; however, there is a lack of up-to-date literature for the nurse to refer to. This article examines the nursing role in chest drain management from insertion to removal and includes aspects of pain management and features of a functioning chest drain. The variety of chest drainage systems now available makes it more important than ever for nurses to understand what's out there and how these systems work. Nurses are responsible for managing chest drains and need to know which drain is best suited for which situation13.

Charnock Y, Evans D conducted a study on “Nursing management of chest drains: a systematic review” with the aim to summarize the best available evidence relating to the nursing management of chest drains. Studies included were those involving hospital patients with a chest drain in situ. A comprehensive and systematic search of the literature was undertaken that included all major databases. Methodological quality was assessed using a developed checklist. The randomized controlled trial (RCT) design was rarely used and therefore evidence was summarized using a narrative discussion. Studies using other methods were also assessed for inclusion in this narrative summary. The findings of this review highlight the lack of research on most aspects of the nursing management of patients with chest drains in situ. RCTs suggest that chest drains remain patent with or without stripping and milking of tubes, but that the total drainage was greater from manipulated tubes. There is little evidence relating to other aspects of chest drain management such as dressing of insertion site, actions following accidental disconnection and tube removal. There is therefore a need for rigorous research in many areas of the nursing management of chest drains, particularly with subjects under the age of 18 years14.

Avilés Serrano M, García Díaz M et al conducted a study on “Thoracic drainage” which says that the Pleural pathology is a frequent clinical problem. In some cases, treatment includes draining the cavity which can be carried out by thoracentesis evacuators, but on occasions treatment requires maintaining a drainage permanently inside the pleural cavity Pleural drainage consists in inserting a catheter in the pleural sack to drain the presence of air; liquid or blood which causes a variable degree of lung collapse having a clinical consequence in function of the reserve breathing capacity the patient previously had and the degree of collapse. There are various models of thoracic tubes as well as systems to drain the pleural cavity and their spot for insertion depends on the type of pathology being dealt with for the patient under treatment. Nursing is fundamental in this entire process, including in the preparation of the patient for this treatment, the insertion of the catheter and the adequate maintenance so that this procedure succeeds as well as during the removal of the catheter and the subsequent care required. It is fundamental that the nursing professionals know the materials used as well as their maintenance. A good technique to cure the punt/orifice where a catheter is inserted will prevent numerous complications which could be deadly for the patient. The authors create a procedural protocol for nurses to use when treating patients who have thoracic drains; this protocol deals with changing the catheters as well as the entire process related to how to treat patients with a pleural drain. This protocol should serve as reference material and as a guide to a systematic and homogenous working procedure. Knowledge of the indications, placement, and management of chest tubes in the intensive care unit is essential for the care of the critically ill patient. Awareness of the complications and mechanical difficulties that can occur with chest tubes and their drainage systems is essential for the safe and effective use of these devices15.

Aylwin CJ, Brohi K et al conducted a study on “Pre-hospital and in-hospital thoracostomy: indications and complications” which says that Pleural drainage with chest tube insertion for thoracic trauma is a common and often life-saving technique. Although considered a simple procedure, complication rates have been reported to be 2-25%. We conducted a prospective cohort observational study of emergency pleural drainage procedures to validate the indications for pre-hospital thoracostomy and to identify complications from both pre- and in-hospital thoracostomies. Data were collected over a 7-month period on all patients receiving either pre-hospital thoracostomy or emergency department tube thoracostomy. Outcome measures were appropriate indications, errors in tube placement and subsequent complications. Ninety-one chest tubes were placed into 52 patients. Sixty-five thoracostomies were performed in the field without chest tube placement. Twenty-six procedures were performed following emergency department identification of thoracic injury. Of the 65 pre-hospital thoracostomies, 40 (61%) were for appropriate indications of suspected tension pneumothorax or a low output state. The overall complication rate was 14% of which 9% were classified as major and three patients required surgical intervention. Twenty-eight (31%) chest tubes were poorly positioned and 15 (17%) of these required repositioning. Pleural drainage techniques may be complicated and have the potential to cause life-threatening injury. Pre-hospital thoracostomies have the same potential risks as in-hospital procedures and attention must be paid to insertion techniques under difficult scene conditions. In-hospital chest tube placement complication rates remain uncomfortably high, and attention must be placed on training and assessment of staff in this basic procedure16.

Gordon PA, Norton JM, Merrell R conducted a study on “Refining chest tube management: analysis of the state of practice” which says that critical care nurses routinely care for patients who require chest tube management. To obtain the best patient outcome, critical care nurses develop standards of practice from research derived recommendations. Although there are several studies recommending chest tube management practices, there is limited research in some areas of chest tube management. The authors analyze the body of research and recommend clinical practice changes and timely research projects on chest tube management17.

Griffiths JR, Roberts N conducted a study on “Do medical staff know where to insert chest drains safely?” which says that the safe insertion of a chest drain is a skill medical staff across specialties require. Incorrect placement can lead to significant morbidity and even mortality.This audit surveyed medical staff working in a teaching hospital about their specialty and level of experience with inter-costal drains. They were then asked to mark on a photograph where they would insert a chest drain for a pneumothorax in a non-emergency situation. Of the 55 medical staff surveyed, 45% were outside the safe area of chest drain insertion as defined by the British Thoracic Society. The most common error was a choice of insertion site too low (24%). In this audit 45% of medical staff surveyed would have placed a chest drain outside the safe triangle recommended by the British Thoracic Society. The common mistake of a choice of insertion site too low should be discussed in in-service teaching programmes18.

Dalbec DL, Krome RL conducted a study on “Thoracostomy” which says that the tube thoracostomy in the Emergency Department is an integral part of trauma and care and treatment of nontraumatic intrapleural collections. An understanding of pleuropulmonary anatomy, physiology, and pathophysiology forms the basis for appropriate and safe application of this procedure. Rapid diagnosis and treatment of intrapleural collections in the trauma patient is essential when one considers the grave prognosis of untreated tension pneumothorax or massive hemothorax. Prior knowledge of possible procedural complications with particular attention to thoracostomy site, sterile technique, and careful blunt dissection makes chest tube placement straightforward and safe. Most post-procedural complications can be avoided through a thorough understanding of the collection system and careful monitoring of the patient19.
