Esophageal malposition is a potentially disastrous complication of attempted airway intubation. We report an unusual case in which a promptly recognized esophageal intubation aided detection of a perforated gastric ulcer. After the endotracheal tube was repositioned and the ulcer was surgically repaired, our patient had an excellent outcome.

We describe a case of catamenial hemothorax and hemopneumothorax occurring on both sides simultaneously; the patient responded remarkably with danazol therapy. To our knowledge, this is previously unreported in the literature.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol vs midazolam in short-, medium-, and long-term sedation of critically ill patients. A cost-benefit analysis.
The purpose of this study was to evaluate and compare the clinical effects, safety, and economic cost of propofol and midazolam in the sedation of patients undergoing mechanical ventilation in the ICU. Eighty-eight critically ill patients were studied and randomly allocated to receive short-term (less than 24 h), medium-term (24 h to 7 days), and prolonged (more than 7 days) continuous sedation with propofol (n = 46) or midazolam (n = 42). Mean doses required were 2.36 mg/kg/h for propofol and 0.17 mg/kg/h for midazolam. ⋯ Recovery of total consciousness was predictable according to sedation time in propofol-treated subgroups (r = 0.98, 0.88, and 0.92, respectively), while this correlation was not observed in the midazolam-treated group. In the subgroup with sedation of less than 24 h, propofol provided a cost savings of approximately 2,000 pesetas (pts) per patient, due to shorter stays in the ICU. We conclude that propofol is a sedative agent with the same safety, higher clinical effectiveness, and a better cost-benefit ratio than midazolam in the continuous sedation of critically ill patients.

Randomized Controlled Trial Clinical Trial
Lack of efficacy of intrapleural bupivacaine for postoperative analgesia following thoracotomy.
Intrapleural bupivacaine has been reported to be effective for analgesia following cholecystectomy and thoracic surgery. Twenty patients who had a posterolateral thoracotomy were studied in a randomized, double-blind, placebo-controlled fashion. Patients were assigned to receive intrapleural administration of either 0.5 percent bupivacaine or saline solution every 4 h for 12 doses postoperatively, as well as narcotic analgesics as needed for additional pain control. ⋯ Two patients who received bupivacaine and three patients who received placebo had development of pneumonia or atelectasis postoperatively. There was no statistically significant difference in any parameter between those who received bupivacaine and those who received placebo. Thus, there was no subjective or objective clinical benefit of this method of postoperative analgesia compared with placebo following posterolateral thoracotomy.

Cytokines have been associated with the development of sepsis and diffuse tissue injury following septic or endotoxic challenges in humans. Furthermore, relative organ-system dysfunction, not specific organ dysfunction, appears to predict outcome from critical illness. We hypothesized that persistence of inflammatory cytokines within the circulation, reflecting a generalized systemic inflammatory response, is associated with multiple-system organ failure (MSOF) and death from critical illness. In addition, since hepatic function is central to host-defense homeostasis, we further reasoned that critically ill patients with hepatic cirrhosis would have an increased incidence of MSOF and death following sepsis associated with a persistence of cytokines in the blood. ⋯ TNF and IL-6 serum levels are higher in septic than in nonseptic shock, but the persistence of TNF and IL-6 in the serum rather than peak levels of cytokines predicts a poor outcome in patients with shock.
