During resection of a Wilms' tumour in a 10-year-old girl, sudden bradycardia, hypotension and cyanosis developed, leading to cardiac arrest. It was thought that part of the tumour had caused a pulmonary embolus. After prompt resuscitation, cardiopulmonary bypass surgery was started within 20 min. At operation the left pulmonary artery was blocked by a tumour embolus which was removed with a Fogarty catheter. The patient is still alive and well 27 months after her operation. We believe her to be the longest surviving patient of this type.

Sonographically detected subacromial/subdeltoid bursal effusion and biceps tendon sheath fluid: reliable signs of rotator cuff tear?

PURPOSE: Our purpose was to determine the association between sonographically detected subacromial/subdeltoid (SA/SD) bursal and biceps tendon sheath effusions and arthrographically proven rotator cuff tears. METHODS: Shoulder sonography reports and sonograms of 105 shoulders in 102 patients who also underwent arthrography were retrospectively reviewed for the presence of fluid within the biceps tendon sheath and SA/SD bursa. Reports and sonograms for 151 asymptomatic shoulders were also reviewed. RESULTS: Biceps tendon sheath effusion and/or bursal fluid were detected in 50 (48%) of 105 shoulders. Fifty-one patients had rotator cuff tears; 28 of them had effusions at 1 or both sites. The sensitivity, specificity, and positive predictive value (PPV) of biceps tendon sheath effusions for diagnosing rotator cuff tear were 35%, 74%, and 56%, respectively. For SA/SD bursal effusions, the sensitivity, specificity, and PPV were 8%, 94%, and 57%, respectively. For combined biceps tendon sheath and bursal effusions, the sensitivity, specificity, and PPV were 12%, 91%, and 54%, respectively. There was no statistically significant association between rotator cuff tears and effusions in the biceps tendon sheath, SA/SD bursa, or both. Among the 151 asymptomatic shoulders, 12 (7.9%) had biceps tendon sheath fluid, 5 (3.3%) had SA/SD bursal effusion, and 2 (1.3%) had both biceps tendon sheath and bursal effusions. CONCLUSIONS: The sonographic detection of intraarticular fluid, SA/SD bursal fluid, or both has a low sensitivity and PPV in the diagnosis of rotator cuff tears. Isolated intra-articular and/or SA/SD bursal effusions are not reliable signs of rotator cuff tear.

Risk factors for postoperative respiratory complications in adult liver transplant recipients.

To determine the types and the incidence of as well as risk factors for early postoperative (<30 days) respiratory complications in adult liver transplant (LT) recipients, we reviewed The data of 44 consecutive adult LT recipients who received their grafts from January 1995 through December 2002. The data included demographic features; primary diagnosis; number of intraoperative transfusions; preoperative and postoperative laboratory values; intraoperative and postoperative characteristics; and early postoperative (<30 days) mortality. Pulmonary atelectasis, pleural effusion, pneumonia, respiratory failure, and pulmonary edema were the respiratory complications investigated. Twenty-six patients (59.1%) developed at least one respiratory complication during the early postoperative period. The most frequent complication was pleural effusion (n = 18, 40.9%), followed by atelectasis (n = 13, 29.5%), pneumonia (n = 10, 22.7%), acute respiratory failure (n = 5, 11.4%), pulmonary edema (n = 3, 6.8%), and pneumothorax (n = 2, 4.5%). Compared to the patients who did not develop these problems, the affected cohort was significantly older (27 +/- 12 years vs 36 +/- 14 years, respectively; P =.039) and required more intraoperative transfusions (P =.005). Among the overall mortality rate of 15.9%, patients who developed pneumonia showed a significantly higher mortality (40.0% vs 8.8%, respectively; P =.037). Pleural effusion, atelectasis, and pneumonia are the main respriatory complications that occur in adult LT recipients. Patient age and intraoperative transfusion requirements are important predictors of early postoperative complications. Pneumonia is associated with a poor prognosis in this patient group.

Percutaneous dilational tracheotomy in solid-organ transplant recipients.

Pulmonary complications, such as pneumonia and respiratory failure, are important contributors to posttransplantation morbidity and mortality among solid-organ transplant recipients. Percutaneous dilational tracheotomy (PDT) is cost-effective in critically ill patients who require prolonged mechanical ventilation; however, the literature lacks reports about the effectiveness of this procedure in organ transplant recipients. Between August 2001 and February 2003, five recipients underwent PDT in our intensive care unit: two kidney, two liver, and one heart transplant recipient. The respective mean values for age, weight and APACHE II score were 41 +/- 7 yrs (range, 33-51 years), 63 +/- 14 kg (range, 40-80 kg), and 23 +/- 9 (range, 15-35). All PDTs were performed at the bedside by an experienced staff anesthesiologist under endoscopic guidance using the Griggs forceps dilational technique. The mean interval from transplantation to PDT was 58 +/- 56 months (range, 8 days to 132 months). In all cases, the indication for PDT was prolonged mechanical ventilation due to acute respiratory failure. The mean duration of endotracheal intubation before PDT was 4 +/- 3 days (range, 1-8 days). Transient hypoxemia (n = 1) and mild extratracheal bleeding (n = 1) were the only early complications. There were no late complications (including peristomal infection) or deaths associated with the procedures. Among the two patients who survived their stay in the intensive care unit, the functional and cosmetic outcomes of PDT were excellent. We recommend this technique for prolonged airway management in solid-organ transplant recipients.
