This prospective study gives short-term results of 208 inguinal herniorrhaphy performed under local anaesthesia. The median age of the 201 patients (186 M, 15 F) was 57 years (17-87). Local anaesthesia could not be achieved in 1 (0.5%) patient because he was panic-stricken. No serious complications occurred. Peroperative systemic hypotension with bradycardia occurred in 6 (3%) cases. Two (1%) benign postoperative sepsis and 9 (4%) hematoma occurred. The median postoperative hospital stay was 2.8 days (1-10). Twenty seven (13%) patients were discharged on the first postoperative day, 93 (46%) in a period of time less than or equal to 2 days, 147 (73%) in a period less than or equal to 3 days and 184 (91%) in a period less than or equal to 4 days.

In this commentary, the impact of the introduction of manual vacuum aspiration (MVA) for incomplete abortion patients and for early uterine evacuation is discussed for the University Teaching Hospital in Lusaka, Zambia. This 3-year training and service delivery program was begun in 1988 after it was clear that 15% of maternal deaths were due to illegally induced abortion. The prior procedure of dilation and curettage (D and C) required use of the main operating room and general anesthesia, which resulted in severe congestion and treatment delays. As a result of the new MVA procedure, congestion has decreased substantially, treatment is safer and more timely, and the staff's ability to provide abortions has increased. Family planning counseling is provided to postabortion patients in a more thorough fashion, and the savings in time has improved the quality of patient-staff interactions. Specifically, the patient flow has improved from a 12-hour wait to a 4-6 hour wait and rarely requires overnight hospitalization. The demand for the main operating room had decreased which frees space, time, and commodities for other gynecological treatment. The shorter procedure and release time means a minimal loss of earnings and productivity, and allows for greater privacy in explaining absences to families, schools, or employers. The improved quality of are is reflected in the figures for number treated, i.e., in 1989, 74% were treated with MVA for incomplete abortion 12 weeks and pregnancy termination 8 weeks compared with 26% treated with D and C. In 1990, the figures were 86% with MVA and 14% with D and C. The likelihood of complications from hemorrhage and sepsis have also been reduced. The MVA procedure is also less traumatic for the patient. The increased access to safe legal abortion services is reflected in the ratio of induced to incomplete abortions between 1988-1990 (1:25 to 1:5). Family planning counseling is provided by a full-time counselor who counsels preabortion and postabortion and schedules 2-week follow-up appointment. These achievements have been made in spite of a declining economy and difficulties in the health sector. Unfortunately, conditions throughout Zambia are such that access to safe abortion is restricted. Effort is underway to expand this MVA training and service delivery in provincial hospitals and to conduct research on other effective strategies to reduced unsafe abortion and improve family planning care.

Sternal sepsis following median sternotomy is an infrequent yet devastating complication of cardiac surgery, leading to prolonged hospitalization, increased hospital expense, and a high associated morbidity and mortality. The development of sternotomy infection is multifactorial. Numerous prospective and retrospective studies have pointed to a multitude of clinical and perioperative variables as being causative, with as many other studies presenting evidence of the contrary. This has led to confusion about which clinical variables should be modified so as to minimize the individual patient's risk for developing this severe complication. Other less obvious factors also come into play. Malnutrition, whether overt or subclinical, is not uncommon in cardiac patients. Immune competency is affected by operative trauma, as well as a variety of perioperative factors including underlying nutritional status, transfusion, cardiopulmonary bypass, and anesthesia. This creates a complex milieu for the development of postoperative infection. In this review, the multiple risk factors of median sternotomy infection are studied and treatment options briefly discussed.

A prospective randomized study was performed with 61 patients undergoing elective surgery for colorectal cancer, to evaluate the prophylactic effect of two different parenteral antibiotic regimens. All patients were randomly allocated into two groups, comparable in age, sex, nutritional status and operative procedures. The patients in Group A (n. 31) received 1 g i.v. of imipenem-cilastatin at induction of anesthesia. Patients in Group B (n. 30) were given cefuroxime (1.5 g i.v.) plus metronidazole (0.5 g i.v.) at the time of anesthesia and two other administrations of the combined antibiotics (cefuroxime 0.75 g plus metronidazole 0.5 g i.v.) every 8 hours. The severity of sepsis was evaluated according to the scoring system proposed by Elebute and Stoner. No significant differences were found in terms of the rate of surgical infections: 9% in Group A and 16% in Group B. Infections not of surgical origin were found only in Group B (10.4%). These data suggest that a single dose of intravenous imipenem-cilastatin appears to be as effective as three doses of cefuroxime and metronidazole as prophylaxis against infection in elective colorectal surgery.

The baboon has a number of advantages as a shock model, as its physiological as well as its biochemical behaviour is similar to man. Therefore we have tried to set up a model to mimic the early hyperdynamic phase of clinical sepsis. Seven baboons, 21-25 kg body weight were kept under EEG servocontrolled anesthesia for 8 hr. During this time live E. coli (ATC #33985) 2 x 10(10) BW/8 hr were continuously infused intravenously. Adequate fluid supply with Ringer's solution (up to 40 ml/kg/hr) was given to keep the pulmonary artery wedge pressure at baseline levels; this procedure resulted in a hyperdynamic response with a cardiac output (CO) 20-35% above baseline and a decrease (20-39%) in mean arterial pressure (MAP), leading to a 50% decrease in peripheral resistance. The pulmonary vascular changes were reflected in an increase of the mean pulmonary pressure (PA) to 42% above baseline and a marked rise in pulmonary vascular resistance (PVR) to 50% above baseline with no additional changes in pulmonary gas exchange. After 8 hr both CO and MAP were inversely correlated (r = 0.9-1) with dramatically increased catecholamine plasma levels (15 times above baseline). With continuous infusion of live E. coli (blood levels 10(5)-10(6) CFU/ml) and massive fluid supply we have successfully mimicked hyperdynamic sepsis with severe organ failure after an 8-hr observation period.

When host antimicrobial defenses are severely compromised by radiation or trauma in conjunction with radiation, death from sepsis results. To evaluate therapies for sepsis in radiation casualties, we developed models of acquired and induced bacterial infections in irradiated and irradiated-wounded mice. Animals were exposed to either a mixed radiation field of equal proportions of neutrons and gamma rays (n/gamma = 1) from a TRIGA reactor or pure gamma rays from 60[Co sources. Skin wounds (15% of total body surface area) were inflicted under methoxyflurane anesthesia 1 h after irradiation. In all mice, wounding after irradiation decreased resistance to infection. Treatments with the immunomodulator synthetic trehalose dicorynomycolate (S-TDCM) before or after mixed neutron-gamma irradiation or gamma irradiation increased survival. Therapy with S-TDCM for mice irradiated with either a mixed field or gamma rays increased resistance to Klebsiella pneumoniae-induced infections. Combined therapy with S-TDCM and ceftriaxone for K. pneumoniae infections in mice exposed to a mixed radiation field or to gamma rays was more effective than single-agent therapy. In all irradiated-wounded mice, single therapy of acquired infections with an antibiotic or S-TDCM did not increase survival. Survival of irradiated-wounded mice after topical application of gentamicin sulfate cream suggested that bacteria colonizing the wound disseminated systemically in untreated irradiated mice, resulting in death from sepsis. In lethal models of acquired infections in irradiated-wounded mice, significant increases in survival were achieved when systemic treatments with S-TDCM or gentamicin were combined with topical treatments of gentamicin cream. Therapies for sepsis in all mice exposed to a mixed field were less effective than in mice exposed to gamma rays. Nonetheless, the data show a principle by which successful therapy may be provided to individuals receiving tissue trauma in conjunction with radiation injury.

The aim of the study reported here was to assess the effects of some clinically relevant factors on the incidence and outcome of postburn bacterial translocation. Miniature pigs in 8 groups (n = 6 in each) underwent: (1) general anesthesia (GA); (2) operation (insertion of Swan-Ganz, arterial, and portal catheters) under GA; (3) burn (40% total body surface area, third degree, under GA); (4) burn and operation; (5) burn, operation, and resuscitation (Parkland); (6) burn, operation, and resuscitation plus endotoxin (100 micrograms/kg IV bolus, 2nd day). Groups 1-6 were killed at 48 hours and tissue samples were harvested for bacteriologic culture. Groups 7 and 8 were the same as 2 and 5, respectively, but were killed at 96 hours. Resuscitation and endotoxin increased postburn bacterial translocation but only endotoxin promoted systemic sepsis. In the absence of additional trauma, translocated bacteria were cleared by 96 hours postburn.

Recently, it has become evident that the gut plays a central role in the development of multiple organ failure in the critically ill patient after trauma-hemorrhage and sepsis. However, it remains unknown whether gut absorptive capacity (GAC) is altered under those conditions. The aim of this study, therefore, was to use a rat model for GAC measurements independent of the function of other organs and to determine whether GAC is altered after trauma. Rats (n = 79; 250-325 g) were lightly anesthetized with ether, and a 6-cm midline laparotomy was performed (i.e., trauma induced). A nasogastric tube was inserted and after cannulation of various blood vessels, the animals were allowed to recover from anesthesia. They were then divided into various groups for determinations of GAC over a period of 5 days. Control animals had GAC measurements without any surgery being performed on them. GAC was determined using the 1-h D-xylose absorption test and measuring D-xylose concentration in the portal blood. Results demonstrate that GAC 1) is significantly depressed for the first 48 h after trauma, 2) returns to normal 72 h after trauma, and 3) is further depressed by hemorrhage and resuscitation and by sepsis after trauma. Thus the model described here can be used to investigate the effects of trauma, trauma plus hemorrhage, trauma plus sepsis, hemorrhage alone, and sepsis alone on GAC, independent of the function of other organs.

Sepsis has been reported to cause mitochondrial dysfunction and inhibition of key enzymes that regulate the tricarboxylic acid (TCA) cycle. We investigated the effect of sepsis on high-energy phosphates, glycolytic and TCA cycle intermediates, and specific amino acids that are involved in regulating the size of the TCA cycle pool during changes in metabolic state of the heart. Sepsis was induced in 12 female rats by the cecal ligation and perforation technique under halothane anesthesia; seven control rats underwent cecal manipulation without ligation. At 36-42 h postsurgery, the rats were reanesthetized, the chest was opened, and the hearts were freeze-clamped. Perchloric acid extracts of the hearts were analyzed with fluorometric enzymatic methods and 31P nuclear magnetic resonance spectroscopy. There were no significant differences in the levels of the TCA cycle intermediates or high-energy phosphates between the septic and control rats. The major metabolic changes were the 28% decrease in alanine and the 31% decrease in glutamate in the septic hearts compared with control (P less than 0.05 and P less than 0.005, respectively). Phosphocholine, a component of membrane phospholipids, was increased by 91% in the septic hearts (P less than 0.01). We conclude that sepsis does not impair the TCA cycle or induce significant cellular ischemia in the heart. The increase in phosphocholine may represent significant cellular membrane disruption during sepsis.

Administration of anaesthesia to patients with sepsis and its effects on the progression of infection in the postoperative period is an important consideration both for surgeons and anaesthetists. All cases of abdominal sepsis carry a surgical mortality of around 50%. Though appropriate therapy is virtually always surgical, limiting initial surgical stress to simple closure and irrigation, supplemented with a proper anaesthetic regime, nutritional care and antibiotic cover, can improve the outcome.
