Low-dose intermittent factor replacement for post-operative haemostasis in haemophilia.

Recommendations for factor replacement therapy for postoperative haemostasis in haemophilia are often empirical and based on the physiological understanding of haemostatic requirements. This report describes the haemostatic management of patients with severe haemophilia undergoing major surgery using lower than usually recommended levels of factor replacement therapy. Eighteen adults (11 with FVIII and seven with FIX deficiency) with an average weight of 52 kg (range: 27-69) underwent 20 major surgical procedures. Factor concentrates were administered by intermittent bolus infusions. The dose of FVIII infused before surgery was 76 mu kg-1 (range: 51-113) and that of FIX was 77 mu kg-1 (range: 50-104). The preoperative levels achieved were 107% (range: 80-180) and 73% (range: 60-90), respectively. Between days 1 and 3 after surgery, an average of 29 mu kg-1 day-1 (range: 20-46) of FVIII and 23 mu kg-1 day-1 (range: 12-42) of FIX was used resulting in mean trough levels of 36% (range: 12-62) and 34% (range: 11-52), respectively. After day 4, an average of 19 mu kg-1 day-1 (range: 15-25) of FVIII and 18 mu kg-1 day-1 (range: 10-37) of FIX was administered until wound healing. The average duration of factor replacement was 11 days (range: 8-16). The mean dose of factor concentrate per patient was 260 mu kg-1 (range: 179-338) of FVIII and 300 mu kg-1 (range: 183-524) of FIX. The total amount of factor used per patient ranged from 12,380 to 19,980 units of FVIII and 8000 to 23,600 units of FIX. Only one patient had post-operative bleeding which was due to a surgical cause. It is concluded that it may be possible to use much lower than recommended levels of factor replacement therapy for postoperative haemostasis in severe haemophilia.

Monitoring of antibiotic use in a primary and tertiary care hospital.

Prophylactic and curative use of antibiotics was studied prospectively in 87 consecutive medical and surgical cases of a tertiary care hospital and in 98 cases of a primary care hospital. Based on Kunins' criteria, antibiotic prophylaxis was found to be more inappropriate in the primary care hospital (49%) than in the tertiary care hospital (34%). Antibiotic therapy, however, was more appropriate at the primary level; 67% as opposed to 60% at the tertiary level. This resulted in a similar overall level of inappropriate antibiotic use in the two hospitals. Surgical prophylaxis was started postoperatively in 68% of the primary care hospital cases. Though prophylaxis was always perioperative in the tertiary care hospital, the postoperative duration was more than 7 days in one third of the cases. The nosocomial infection rate in those given prolonged prophylaxis was higher than those who received antibiotics for less than 72 hours. Antibiotics were started empirically in 78% of tertiary hospital care cases and 100% of cases in the primary hospital. Though culture sensitivity was done in 80% of the tertiary care cases, more than half the specimens were sent after multiple doses of antibiotics were started. The choice of antibiotic did not always correlate with the sensitivity report. Though cost-effective drugs were chosen in 50% of cases, in more than 20% of cases expensive drugs were started. The study highlights the need for an antibiotic audit and suggests the necessity of having an ongoing peer audit.

Bull horn injuries.

Bull horn injury is not uncommon, and during a 12 year period from 1977 to 1988, 101 patients required inpatient treatment at the Christian Medical College Hospital, a teaching hospital at Vellore in South India. The ages of these patients ranged from two years to 90 years and the male to female ratio was 4:1. Sixty-one per cent of the injuries occurred either to the perineum or abdomen and wounds were directed obliquely upward. Thirty-five per cent required extensive surgical intervention. The over-all wound infection rate was 12.9 per cent. Of wounds that were primarily closed, 42.9 per cent had wound infection, while only 6.3 per cent that were secondarily closed developed infection. Two patients died as a consequence of the injury. Based on the results of this study, we recommend that a careful evaluation of the injury and timely and appropriate management of each patient must be done to reduce morbidity and mortality. Primary closure of wounds must be avoided even when surgical intervention is possible soon after injury.

Typhoid ileal perforations: a retrospective study.

This report examines the characteristics of 124 patients with typhoid ileal perforation treated over a 17-year period ending in 1986. Three adverse prognostic determinants were identified: prolonged fever/perforation interval, prolonged perforation/operation interval and multiple perforations. Simple closure was performed in 74 patients with a mortality of 31.1%, and trimming of the ulcer with closure in 38 patients with a 7.9% mortality.
