Managing pain during mediastinal chest tube removal.

OBJECTIVE: To compare four analgesic regimens used in preparing patients for chest tube removal. DESIGN: Prospective, randomized, controlled multiple-group comparison. SETTING: Mid-atlantic university affiliated tertiary medical center. PATIENTS: 80 adult patients who underwent heart surgery and who had two mediastinal chest tubes. OUTCOME MEASURES: Subject's pain intensity rating on a 0 to 100 mm visual analog scale and subject's description of sensations blindly rated by six nurses. INTERVENTION: Before chest tube removal, subjects were medicated with either: (1) intravenous morphine sulfate (morphine), (2) intravenous morphine and subfascial angiocatheter lidocaine hydrochloride (lidocaine), (3) intravenous morphine and subfascial angiocatheter normal saline solution, or (4) subfascial angiocatheter lidocaine. RESULTS: Mean pain rating scores for groups 1, 2, 3, and 4 were 43.7 40.9, 36.4, and 38.1, respectively. Analysis of variance showed no significant difference between scores (p = 0.8948). The percentage of comments rated as "not bad at all" or "not bad" for groups 1, 2, 3, and 4 were 56%, 83%, 47% and 75%, respectively. Chi-square analysis showed a significant difference between ratings (p < 0.01). CONCLUSIONS: Blind ratings of subjects' descriptions of sensations suggest subfascial lidocaine may be useful in reducing discomfort during chest tube removal.

Doxycycline pleurodesis in rabbits: comparison of results with and without chest tube.

We have reported previously that there is a high incidence of hemothorax and substantial mortality in rabbits that are given tetracycline derivatives intrapleurally. However, such complications have not been reported in humans when pleurodesis is attempted with tetracycline derivatives. One primary difference in the two situations is that a chest tube is placed only in humans. The objective of this study was to evaluate the hypothesis that chest tube placement would prevent the development of hemothoraces and lead to better pleurodesis in rabbits given doxycycline intrapleurally. Eighty New Zealand White male rabbits received doxycycline, 20 mg/kg, in a total volume of 2 mL. One half of the rabbits were randomized to receive a chest tube at the time of the injection and were subjected to pleural fluid aspiration twice daily. The remaining rabbits (control group) received no chest tube and no aspiration. Ten rabbits from each group were killed on days 4, 7, 14, and 28. The intrapleural injection of doxycycline induced the production of large exudative effusions. The insertion of chest tubes prevented the development of hemothorax (0/20 in chest tube group, 15/20 in control group, p<0.001). The insertion of chest tubes was also associated with a significant reduction in mortality and a significant improvement in pleurodesis. When pleurodesis is attempted in rabbits with intrapleural doxycycline, the insertion of a chest tube will prevent hemothorax and lead to a better pleurodesis.

A comparison study of chest tube thoracostomy: air medical crew and in-hospital trauma service.

Chest tube thoracostomy (CTT) is not frequently performed by non-physician-staffed air medical crews (AMC) due to concern regarding safety, efficiency and training requirements. This study compared two groups of patients requiring CTT, one group with insertion performed by an AMC and the other by a physician trauma service (TS) in the emergency department on patient arrival. The CTT of 172 patients managed at a Level I trauma center between October 1988 and September 1990 were reviewed. Seventy-two patients were managed by the AMC and received CTT in a prehospital setting; the air medical personnel placed the chest tube cleanly in all cases. Chest tubes placed by AMC were removed within 48 hours of transport to minimize infection risk. One hundred patients requiring CTT in the hospital setting were randomly selected from the trauma registry during a similar time span. The study compared the patients' Injury Severity Scores (ISS), and trauma scores, any placement complications and the overall mortality. While the AMC often treated patients with higher acuity, as reflected by ISS and trauma scores and overall higher mortality, the rate of complications between CTT performed by AMC and TS was similar. Appropriately trained AMC can safely perform CTT without putting patients at increased risk.

Ectopic chest tube insertions: diagnosis and strategies for prevention.

In the six-month period from October 1999 to March 2000, the authors carried out a prospective study of ectopic chest tube placements (ECTP) diagnosed at the Assir Central Hospital, Abha, Saudi Arabia. During the reference period, 63 chest tube placements were carried out in 44 patients while one patient was from a medium-sized general hospital within a neighbouring city. The grades of the surgeons who had performed the ECTP were: surgeon specialists based at peripheral hospitals--5 (83.3%), and surgical resident in training at the regional referral centre--1 (16.7%). Mean age = 29.7 years; M:F ratio = 2:1. A total of 6 cases of ECTP were found constituting 9.5% of all chest tube insertions mostly from small hospitals situated in the peripheral, non-urban areas. The diagnosis of ECTP was made on plain chest radiographs in 3 patients (50%) and on the CT scans of the chest in 3 patients (50%). The ECTP was into the lung (2 cases--33.3%), subdiaphragmatic. intraabdominal (3 cases--50%), and chest wall, subcutaneous (1 case--16.7%). Misdiagnosis and failure to carry out a finger exploration of the pleural cavity prior to the placement of the chest tube rather than the use of chest tubes with trocars was to blame. The incidence of ECTP (9.5%) is high and underlines the need for proper training in the methodology of chest tube insertion for junior surgical cadre.

Pigtail catheters versus large-bore chest tubes for pneumothoraces in children treated in the emergency department.

OBJECTIVE: We sought to compare the efficacy (pneumothorax resolution and hospitalization days), pain (narcotic usage), and safety (need for repositioning or replacement) associated with placement of large-bore chest tubes versus pigtail catheters in children with pneumothoraces. METHODS: We conducted a retrospective chart review of all patients with pneumothoraces seen in the emergency department (ED) over a 6.5-year period who received treatment by a pediatric emergency physician with either a large-bore chest tube or a pigtail catheter. We excluded patients who had catheters placed by other specialists and patients who were endotracheally intubated. We collected the following data: complications, hospital days to discharge, and narcotic pain medications taken. RESULTS: Eleven pigtail catheters and 16 large-bore chest tubes were placed. All pneumothoraces were effectively evacuated. Three of the 11 pigtail catheters required repositioning, and one was replaced. Two of the 16 large-bore chest tubes were repositioned, and one was replaced; additionally, a pigtail catheter was added to one patient with a large-bore chest tube to facilitate evacuation of the air. Average hospital stay was similar between groups (6.2 d for pigtail catheters vs 6.8 d for large-bore chest tubes, = 0.74). Children with pigtail catheters required less narcotic pain medications than those who had large-bore chest tubes, but the differences were not significant. CONCLUSION: Pigtail catheters offer a safe and effective alternative to large-bore chest tubes for patients receiving treatment for pneumothoraces in the ED.

Techniques for chest tube insertion and pleurodesis. An updated look at two common procedures.

Chest tube insertion is warranted for drainage of large exudative pleural effusions, empyemas, hemothoraces, or chylothoraces, and for some pneumothoraces or parapneumonic effusions. Chest tubes may also be used to instill sclerosing agents to prevent recurrent malignant effusions or pneumothorax. There are no absolute contraindications to tube thoracostomy; however, if time allows, effort should be made to correct any coexisting hemorrhagic disorders before the procedure is performed. Pleurodesis may be contraindicated in patients who are expected to undergo lung surgery. The incisional method is safest for chest tube insertion and pleurodesis; bear in mind, however, that some patients with pneumothorax may be better treated with small-caliber drainage.

Refining chest tube management: analysis of the state of practice.

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 management.

A simple technique for anchoring chest tubes.

Although some techniques have been described for securing chest tubes, many complications are still reported. A simple method is described for securing chest tubes and closure of the wound, resulting in good fixation of the tube and an airtight closure of the chest wall with a cosmetically satisfactory result.

Improvised chest tube drain for decompression of an acute tension pneumothorax.

A case of a woman presenting with an acute tension pneumothorax during a Navy humanitarian mission in East Timor is presented. The patient was treated at a local rural clinic run by our medical team. Prompt insertion of a chest tube saved the woman's life; however, there were no chest tube drains available. A field chest tube drain constructed out of an IV bag, a sterile water bottle, and tubing provided an adequate underwater seal and drain. Because of the remote location and limited resources, standard prehospital chest tube management had to be modified. A brief review of simple and tension pneumothoraces and management along with a description of the field chest tube drain is presented.

Manual aspiration versus chest tube drainage in first episodes of primary spontaneous pneumothorax: a multicenter, prospective, randomized pilot study.

Although there is no agreement on the optimal treatment of patients presenting with a first episode of primary spontaneous pneumothorax, the majority of physicians prefer chest tube drainage for air evacuation. Manual aspiration of air has been proposed by some, but lack of sound comparative data and safety data has limited its use. In this first randomized, prospective, multicenter pilot study, 60 patients with a first episode of primary spontaneous pneumothorax were randomly allocated to manual aspiration (n = 27) or chest tube drainage (n = 33). Immediate success was obtained in 16 out of 27 (59.3%) in the manual aspiration group, and in 21 out of 33 (63.6%) in the chest tube drainage group (p = 0.9). One-week success rates were 25 out of 27 (93%) in the intention-to-treat manual aspiration group and 28 out of 33 (85%) in the chest tube drainage group (p = 0.4). Fourteen of 27 manual aspiration patients (52%) were hospitalized, versus 100% of the chest tube drainage patients (p < 0.0001). Recurrence rates with at least 1-year follow-up were 7 out of 26 (26%) in the manual aspiration group, and 9 out of 33 (27.3%) in the chest tube drainage group (p = 0.9). There were no complications associated with manual aspiration. Although statistical power is insufficient to formally confirm therapeutic equality, this pilot study suggests that in first episodes of primary spontaneous pneumothorax, manual aspiration seems equally effective as chest tube drainage and is safe, well tolerated, and feasible as an outpatient procedure in the majority of patients.

Conservative use of chest-tube insertion in children with pleural effusion.

The aim of this work was to evaluate the effect of a more conservative use of chest-tube insertion on the short-term and long-term outcome of pleural infection. Sixty-five patients with pleural infection, aged 1 month to 16 years were each treated according to one of the two protocols: classical management with chest-tube insertion (classical group, n = 33), or conservative use of chest-tube insertion (conservative group, n = 32), with drainage indicated only in the case of voluminous pleural effusion defined by a mediastinal shift and respiratory distress and/or an uncontrolled septic situation. The two groups were comparable with regard to age, baseline C-reactive protein (CRP) value and white blood cell counts, pleural thickness, identified bacteria, and antibiotic treatment. Chest-tube insertion was performed in 17 patients (52%) of the classical group compared to eight patients (25%) of the conservative group (P = 0.03). Duration of temperature above 39 degrees C was shorter in the conservative group (10 +/- 1 vs. 14 +/- 1 days, P = 0.01), as was the normalization of CRP (13 +/- 1 vs. 17 +/- 1 days, P = 0.03). Duration of hospitalization and intravenous (IV) antibiotherapy as well as the delay of chest-radiograph normalization was not significantly different between the two groups. A more conservative use of chest-tube insertion did not change short- and long-term outcome of the pleural infection in children. Drainage could be restricted to the most severely affected patients with pleural empyema causing a mediastinal shift and respiratory distress and/or presenting with an uncontrolled septic situation.

The management of chest tubes in patients with a pneumothorax and an air leak after pulmonary resection.

BACKGROUND: Placing chest tubes to water seal is superior for patients with an air leak, but when a patient has a pneumothorax and an air leak the best chest tube setting is unknown. METHODS: This is a retrospective analysis of a prospective database on a consecutive series of patients who had a pneumothorax and air leak on the same day. Patients underwent elective pulmonary resection by one surgeon and had their chest tubes placed to water seal on postoperative day 1. Daily chest radiographs were obtained, and the size of the pneumothorax and air leak were measured. Tubes were left on seal unless there was a symptomatic enlarging pneumothorax or subcutaneous emphysema (defined as failing water seal). The primary objective was to evaluate the efficacy of water seal. We also wanted to identify risk factors that predicted failure of water seal. RESULTS: There were 838 patients > or = 21 years old who underwent elective pulmonary resection, and 86 patients (10%) had an air leak and a concomitant pneumothorax on the same day. Fourteen patients (16%) failed water seal. Multivariate analysis showed that a large air leak (greater than or equal to expiratory 3 in our classification system; odds ratio [OR], 16.5; p < 0.001) and a pneumothorax > 8 cm in size (OR, 4.9; p < 0.005) were predictors of failing water seal. CONCLUSIONS: Keeping chest tubes on water seal is safe for most patients with an air leak and a pneumothorax. However, if the leak or pneumothorax is large, then subcutaneous emphysema or an expanding symptomatic pneumothorax is more likely. A prospective randomized trial is needed to compare water seal to suction in these patients.

Chest tube stripping in pediatric oncology patients: an experimental study.

BACKGROUND: Stripping of chest tubes to promote drainage of the thorax of postthoracotomy patients has been routine practice, based on tradition. Recent published findings indicate that significant negative pressures are generated in the tube during stripping that could cause pain, bleeding and possible damage to the patient's lung tissue. OBJECTIVE: To determine whether pediatric oncology patients whose chest tubes were not stripped would differ in frequency of pain, fever or lung complications from patients who underwent routine tube stripping. METHODS: Data were collected at multiple points during the first 72-hour postoperative period from 16 patients assigned to the stripped or unstripped groups. Pain was measured by the Faces Pain Scale and the Visual Analogue Scale; temperature, by electronic thermometer; and lung complications, by stethoscope and radiographs. Both groups, which were comparable for age, primary diagnosis and prior history of lung problems, received identical supportive nursing and medical care, with the physicians blind to group assignment. RESULTS: The two groups did not differ significantly in frequency of pain, incidence of fever, breath sounds or radiographic findings across measurement points. A strong correlation was found between the pain scores using the two instruments. DISCUSSION: Patients whose tubes were not stripped did not have an increased risk of infection or lung complications. Study findings indicated that stripping did not increase the frequency of pain. CONCLUSIONS: Stripping of chest tubes as a routine postoperative measure is questioned.

[Limits of duration of chest tube drainage in the first episode of spontaneous pneumothorax].

We treated three patients with spontaneous left pneumothorax who underwent a long period of chest tube drainage before surgery. Case 1 was a 61-year-old man. On day 13 after drainage started, much air leakage occurred and surgery was done the next day. Case 2 was a 57-year-old man. Drainage failed to allow the air leakage to seal. The patient did not consent to surgery for about a month, but on day 38 after drainage started, he underwent surgery. Case 3 was a 19-year-old man. First, chest tube drainage was successful and he was extubated on day 16. However, pneumothorax recurred the next day. Liver dysfunction delayed surgical treatment, and the patient underwent surgery on day 54 after the first drainage. Postoperatively, he developed wound infection of the chest tube route and aseptic pleurisy of unknown origin. Limits of duration of unsuccessful chest tube drainage for the first episode of spontaneous pneumothorax are controversial. These cases suggest that when two weeks of chest tube drainage is unsuccessful, surgery should be undertaken in view of postoperative complication and social indications.

Effects of two chest tube clearance protocols on drainage in patients after myocardial revascularization surgery.

The purpose of the study was to determine the effects of two methods of clot clearance on chest tube drainage in patients undergoing myocardial revascularization. Two hundred adult patients immediately after myocardial revascularization were randomly assigned to a specific chest tube manipulation group. The dependent variables were drainage, incidence of cardiac tamponade, incidence of surgical reentry, hemodynamic values, and number of manipulation episodes. Statistical analyses revealed no difference in any of the dependent variables when milking and stripping were used. Of the 200 patients, 78 did not require any manipulation of the chest tubes in the first 8 hours after surgery. One patient had signs of cardiac tamponade and six other patients required surgical reentry. Positioning of the connecting tube in a nondependent position assisted with the removal of drainage from the chest cavity. In conclusion, patients having myocardial revascularization did not need their chest tubes manipulated the first 8 hours after surgery. Visible drainage in the chest tube did not cause a lack of patency.

[Video-assisted thoracoscopic access in pleural empyema compared with mere chest tube drainage].

Video-assisted thoracoscopic (VAT) debridement is gaining importance in the fibrino-purulent phase of empyema thoracis. However, evaluation of this access compared with mere chest tube drainage or thoracotomy remains unsatisfactory. A total of 356 parapneumonic empyemas from 1986 to 1997 were retrospectively analyzed concerning the results after primary treatment (chest tube 225, thoracotomy 80, VAT 51). The three groups did not differ significantly for gender and associated diseases. Median age of the chest tube drainage group (54 years) was higher than for thoracotomy (43.5 years) or VAT (39 years). Median duration of chest tube treatment after thoracotomy (7 days) was shorter than after VAT (13 days) or chest tube drainage (20 days) (P < 0.0001). The more invasive procedures were also superior to the lesser invasive treatment concerning duration of postoperative hospitalization, recurrence rate and treatment failures. In spite of its better results thoracotomy will be pushed back by VAT in the treatment of empyema thoracis. Acceptance of VAT is reflected in rising numbers of admissions. Based on these retrospective results we are planning a prospective multicenter trial to evaluate the indication for VAT in empyema thoracis.

Chest tube perforation of esophagus following repair of esophageal atresia.

The two major acute thoracic complications of closed chest tube thoracostomy are pulmonary laceration and vascular compression. We have noted that closed chest tube thoracostomy can also perforate an esophageal anastomosis or myotomy site. Clinically, such a perforation produces a profuse discharge of gas and/or fluid through a chest tube positioned at the level of the anastomosis or myotomy site. Plain films demonstrate an accumulation of extrapleural gas and/or fluid adjacent to the distal portion of the chest tube. If untreated, these accumulations may form into an extrapleural abscess.

Acute diaphragmatic paralysis caused by chest-tube trauma to phrenic nerve.

A 3 1/2-year-old child developed unilateral diaphragmatic paralysis after chest drain insertion. Plain chest X-ray demonstrated paravertebral positioning of the chest-tube tip, and magnetic resonance imaging revealed hematomas in the region of the chest-tube tip and the phrenic nerve fibers. The trauma to the phrenic nerve was apparently secondary to malposition of the chest tube. This is a rare complication and has been reported mainly in neonates. Radiologists should notify the treating physicians that the correct position of a chest drain tip is at least 2 cm distant from the vertebrae.
