The hospital and ICU course of 98 patients who required mechanical ventilatory support longer than 72 h was reviewed to determine if mortality rates were influenced by admitting diagnosis. Patients with malignant diagnoses were compared to patients with nonmalignant diagnoses and to those admitted to the ICU after myocardial infarction or cardiorespiratory arrest. Although there was no significant intergroup difference in incidence of multiple organ system failure, age, and length of ICU and hospital stay, there was a much higher incidence of sepsis (p less than .05) and mortality (p less than .01) in the cancer group. Cancer patients and their families should be made aware of the extremely poor prognosis if prolonged acute respiratory failure develops.

Between 1970 and 1983, 46 patients were hospitalized in the Vanderbilt University Medical Center and the Metropolitan Nashville General Hospital for treatment of achalasia. All patients had been symptomatic for at least two years. Efforts were made initially to manage most of these patients (40) with periodic esophageal dilatation. This was successful in only six cases (15%). In four instances (10%), patients had esophageal perforation. Thirty patients have had esophagomyotomy (Heller procedure), and 14 of these had an associated antireflux procedure. Three had proximal gastric vagotomy for associated duodenal ulcer disease. Twenty-seven (90%) have had a good result, three died postoperatively, and two elderly patients had postoperative myocardial infarction. The other patient had sepsis after repair of a perforated esophagus. While periodic esophageal dilatation is necessary in patients who may not tolerate an operative procedure, most patients with achalasia are best treated with Heller esophagomyotomy.

The results of a prospective study of ventricular electrical instability after myocardial infarction (MI) are presented. Ventricular electrical stability was assessed using a standardized protocol of programmed stimulation in 165 hemodynamically stable patients 6 to 28 days after acute MI. Ventricular electrical instability was defined as induction at programmed stimulation of ventricular fibrillation (VF) or ventricular tachycardia (VT) lasting at least 10 seconds. Of 165 MI survivors, 38 (23%) had ventricular electrical instability. No significant differences were noted between stable and unstable patients in terms of coronary prognostic index, elevation of serum creatine phosphokinase, coronary anatomy, site of MI, or frequency of VT within 48 hours of MI. The mean follow-up period was 8 months (range 0 to 12). There were 7 deaths in stable patients (5 from cardiogenic shock, 1 from septicemia, and 1 unwitnessed) and 10 deaths in unstable patients (8 instantaneous, 1 from cardiogenic shock, and 1 unwitnessed) during the subsequent year. In addition, 2 of 127 stable patients and 4 of 38 unstable patients had spontaneous VT from which they were satisfactorily resuscitated. Thus, the sensitivity of ventricular electrical instability as a predictor of instantaneous death or spontaneous VT was 86% and the specificity 83%. The predictive accuracy of the absence of ventricular electrical instability as an indicator for the absence of instantaneous death or spontaneous VT was 98%. The predictive accuracy of the presence of ventricular electrical instability as a predictor of instantaneous death or spontaneous VT was 32%. Thus, patients with ventricular electrical instability after MI have a high risk of instantaneous death within 1 year; patients without ventricular electrical instability after MI have a low risk of instantaneous death within 1 year; prospective studies of antiarrhythmic therapy and measures to prevent reinfarction and optimize left ventricular performance are required to determine whether instantaneous death can be prevented in unstable patients; and therapy to prevent reinfarction and optimize left ventricular performance may offer the best chance to improve prognosis in stable patients.

The authors evaluated the effectiveness of 6% hydroxyethyl starch (hetastarch) solution for treatment of hypovolemia in 46 critically ill patients. Thirty-two of the patients were studied retrospectively and in 14 patients, cardiopulmonary variables were prospectively measured. A total of 29 patients were in shock secondary to hypovolemia (13), sepsis (13), or myocardial infarction (3). Average hetastarch infusion volume was 829 and 842 ml, respectively, in prospectively and retrospectively studied patients, with maximum of 2000-2500 ml infused over 48 h. Approximately 30% of 24 h fluid needs were supplied with colloids. Infusion of 500 ml of hetastarch in 14 prospective study patients was associated with increases in pulmonary artery wedge pressure (WP) from 9 +/- 1.5 to 12 +/- 2.1 mm Hg, cardiac index (CI) from 2.9 +/- 0.2 to 3.5 +/- 0.3 (p less than 0.05) along with an increase in mean arterial pressure (MAP) from 87-99 mm Hg and reduction in arteriovenous O2 difference [C(a-v)O2] from 4.9 to 4.2 ml/dl. Intrapulmonary shunt (Qsp/Qt) was similar (20 vs. 21% as were alveolar-arterial O2 gradient [P(A-a)O2] (164 vs. 158 torr), whereas O2 consumption (VO2) increased from 224 to 247 ml/min. Immediate survival was 90% in shock patients and 100% in nonshock patients, whereas hospital survival was 65.5% and 88%, respectively. The authors conclude that hetastarch is an effective fluid for resuscitation of hypovolemic patients. This synthetic colloid does not appear to adversely affect pulmonary function.

The cases of 135 consecutive elderly patients 70 years old or older who had valve replacement and related surgical procedures from October, 1977, through April, 1982, were reviewed. There were 75 men and 60 women. The mean left ventricular ejection fraction was 50.16 +/- 5%. The overall operative mortality was 8% (11 patients). The early operative deaths were related mainly to cardiac failure, low cardiac output, sepsis, and renal and multiorgan failure. To assess the operative risk, these 135 patients were compared with 312 younger patients (less than 70 years old) who had undergone similar procedures during the same period. The operative mortality in this group was 5.2% (16). In-hospital complications included arrhythmia (13%), psychosis (7.4%), respiratory failure (6.7%), renal failure (6.7%), cerebrovascular accident (5.2%), myocardial infarction (4.4%), and reoperation for bleeding (2.2%). Wound dehiscence occurred in 1.5% of the patients, and pulmonary emboli and sepsis developed in 0.7%. Of these complications, only the incidence of cerebrovascular accident appeared to be more common in the elderly group (5.2% versus 2.8%), but it had no statistical significance (p = 0.18). A follow-up of 3,892 patient-months was completed in 98.4% of the survivors. There were 8 late deaths (6.4%). Six were related to the valve or to ongoing cardiovascular disease. Thirty-four patients subsequently required medical attention: 4 had bleeding because of the anticoagulant; 3 required a blood transfusion; and 27 were hospitalized. Six were admitted for related cardiac conditions and 7, for observation of other conditions; 14 underwent surgical procedures not related to the cardiovascular system.(ABSTRACT TRUNCATED AT 250 WORDS)

The complement (C) system evolved as a beneficial antimicrobial system. However, when activated during extracorporeal perfusion as with haemodialysis or cardiopulmonary bypass modest pulmonary dysfunction associated with granulocyte aggregation and embolization can occur. When C activation is massive and prolonged, as with severe sepsis, trauma, or acute pancreatitis, severe pulmonary damage which is recognized as shock lung, or adult respiratory distress syndrome, may occur. Since ulcerating atherosclerotic plaques can also activate C, a mechanism by which myocardial infarcts may extend during the first few hours after infarction is also implied. Therapeutic ramifications of these conclusions are evident. Thus, high doses of corticosteroids or of nonsteroidal anti-inflammatory agents such as ibuprofen share the ability to prevent aggregation and embolization of stimulated granulocytes to patent vessels downstream and also inhibit their production of toxic oxygen radicals. These properties suggest the use of these agents in myocardial infarction and shock states, particularly shock lung, and appropriate clinical trials are awaited with interest.

In a prospective randomized study of treatment for early-stage Hodgkin's disease presenting above the diaphragm, 76 patients had staging by laparotomy (Group I) and 28 had staging by closed techniques (Group II). Treatment consisted of involved-field radiotherapy alone (44 patients), involved-field radiotherapy followed by chemotherapy (38 patients), total nodal radiotherapy alone (15 patients), or total nodal radiotherapy followed by chemotherapy (seven patients). On presentation, both groups had similar clinical features and similar treatment distribution. With similar follow-up (87 months), no significant differences in remission or survival were observed between Groups I and II: remission 59 versus 68 percent; survival 74 versus 92 percent; p value 0.27 and 0.09, respectively. Multiple areas of relapse were more frequently observed in Group I (11 of 32 had relapse) as compared with Group II (none of nine had relapse, p less than 0.082). In Group I, relapse in the abdomen was observed as an isolated event or as part of disseminated relapse in 12 percent of patients compared with 3 percent (one patient) in Group II with abdominal relapse alone. Seven patients in Group I and two patients in Group II died with Hodgkin's disease. Six other patients in Group I died with complete remission of non-Hodgkin's lymphoma (one patient), leukoencephalopathy (one patient), sepsis during chemotherapy (two patients), myocardial infarction (one patient), and cerebrovascular accident (one patient). Three other patients in this group had other secondary malignancies successfully controlled (histiocytic lymphoma, squamous cell carcinoma of the cervix, and malignant schwannoma). No second primary lesions or death with complete remission were observed in Group II. Staging laparotomy with splenectomy in early-stage Hodgkin's disease did not improve the duration of remission or survival or decrease the number of abdominal relapses compared with closed staging.

Intrahepatic cholelithiasis is commonly associated with suppurative cholangitis and occurs equally in males and females. Patients usually present with a history of recurrent symptoms and a differential diagnosis which includes viral hepatitis, pancreatitis, myocardial infarction and perforated ulcer. Cholangiography including stereocholangiography is essential for localizing intrahepatic stones and ductal strictures. The guiding operative principle is to drain all infected bile distal to ducts obstructed with stones or stricture. This may also necessitate a bilioenterostomy with or without partial hepatic resection. Although these procedures are formidable in an acutely ill patient, a more simple but inappropriate choledocholithotomy and t-tube drainage done proximal to an obstructed intrahepatic duct will be ineffective and may result in continued sepsis and death.

Sixteen episodes of ventricular tachycardia and/or fibrillation, 12 of which occurred during shaking chills, were recorded in six patients with septicemia. All patients were greater than 60 years of age and had suffered a previous myocardial infarction. Patients who survived the condition sustained no further arrhythmias during a follow-up period of 1 to 4 years, despite the fact that no antiarrhythmic medication was administered. It is suggested that patients greater than 60 years of age who had suffered a previous myocardial infarction should be carefully monitored during septic episodes and especially during shaking chills, since these may represent vulnerable periods facilitating the precipitation of potentially lethal arrhythmias.

The marked conjugated hyperbilirubinemia in a 72-year-old patient with myocardial infarction and sepsis is reported. The serum bilirubin, which was predominantly composed of conjugated bilirubin, was elevated to 21 mg/100 ml, while serum bile acid and alkaline phosphatase levels were normal or slightly elevated. Postmortem examination of the liver revealed slightly proliferated bile ductules and some bile thrombi with little liver cell necrosis.
