Comparative Study
Sepsis in the baboon: factors affecting resuscitation and pulmonary edema in animals resuscitated with Ringer's lactate versus Plasmanate.
Septic shock and the formation of pulmonary edema were studied in 19 baboons. Four animals served as controls. Four were subjected to deep septic shock by infusion of live E. coli and then deliberately killed while in deep shock. ⋯ There was an increased tendency for albumin to extravasate into the interstitium of the lungs after resuscitation. The amount of pulmonary edema, measured by both the thermodye technique and by analysis of post-mortem lung composition, was the same in animals resuscitated with RL and PL. Administration of pure colloid offers no protection to the lungs in resuscitating patients from septic shock.

One hundred twenty-three patients with lower chest and abdominal stab wounds were evaluated. If chest wounds were located between the two anterior axillary lines and abdominal examination was negative, peritoneal lavage was performed. If abdominal wounds were located between the two anterior axillary lines and physical examination was negative, local exploration was performed followed by lavage if local exploration was positive. ⋯ Of the patients in this selected series 69.9% were spared an operative procedure. The incidence of negative laparotomy was 4.1%. It is concluded that the combination of local exploration and peritoneal lavage will increase diagnostic accuracy, eliminate unnecessary hospitalization, and reduce the number of negative laparotomies.

The natural history of electrical injury, exclusive of electrical flash burns, was determined in 64 patients. These patients sustained relatively small burns (x=11%); only nine patients (14%) had burns greater than 25%. Forty-six patients suffered 114 major complications. ⋯ Early patient referral and vigorous fluid resuscitation minimized renal failure (1.5%) and mortality (3.1%). Early fasciotomy and vigorous debridement appeared to decrease wound sepsis (8%), but apparently had little if any effect on major limb salvage. The unsolved problems of electrical injury, namely neurological and vascular sequelae, are major contributors to the high morbidity of electrical injury.

The treatment of penetrating thoracic injuries has been reviewed in both civilian and military series. Although most surgeons agree that closed that closed thoracostomy drainage is the initial treatment of choice, the timing of early thoracotomy and perhaps cardiorrhaphy upon patients with penetrating thoracic injuries remains controversial. The purpose of this study was to determine which patients will require immediate thoractomy or cardiorrhaphy following penetrating chest injury. ⋯ The mortality rate was related to exsanguinating hemorrhage or postoperative intra-abdominal sepsis. Cardiopulmonary complications were rare in the absence of intra-abdominal sepsis and could not be attributed to the thoracic injury or thoracotomy. Indications for immediate cardiorrhaphy or thoracotomy are: 1) location of the entrance wound (70% in upper mediastinum); 2) blood pressure on admission less than 90; 3) initial thoracostomy blood loss greater than 800 cc; 4) radiographic evidence of retained hemothorax; and/or 5) clinical evidence of pericardial tamponade.

The case report of an atrial septal defect with right-to-left shunting in an adult following blunt chest trauma is presented. To our knowledge a successfully repaired traumatic atrial septal defect has not been previously reported in the English-language literature.
