Prophylactic antibiotics in transurethral prostatectomy.

The study included 88 patients with sterile urine prior to transurethral prostatectomy. Forty-five received a preoperative dose of 2 g of cefotaxime (Claforan) and the remaining 43 were given 10 ml of 0.9% NaCl. The two groups did not differ in frequency of postoperative urinary infection (greater than 10(5) colonies per ml urine); 6 patients (13.3%) in the cefotaxime group had postoperative infections during hospital stay as compared to 8 patients (18.6%) in the control group (0.5 greater than p greater than 0.3). Those in the cefotaxime group who had infections were tested for resistance. They were all fully sensitive to cefotaxime except one, who was infected with enterococci. There was no growth of bacteria from either venous blood or bladder irrigating fluid taken during the operations. Nor were any serious complications observed in any of the patients. In view of the relatively low risk of infection and the few side effects of the infections that did occur, prophylactic treatment with an antibiotic is not indicated for transurethral prostatectomy in patients with sterile urine.

Conization of the cervix uteri. Complications in connection with plain catgut or silk suturing.

During a retrospective study on postoperative complications in 213 patients who had undergone conization, a (non-significant) reduction in the bleeding rate from 27.9% to 18.6% was found when using silk sutures (102 patients) instead of plain catgut (111 patients) for adaption of the edges of the wound (0.1 less than p less than 0.2). The reduction was most pronounced and significant in cases where bleeding had occurred during the first 4 days after surgery, the usual period for hospital stay under normal conditions. After discharge the bleeding rates were more comparable, 12.6% in the catgut group and 16.6% in the silk group. On the other hand, more cases of stenosis of the cervical canal were observed, i.e., 25.5% in the silk group and 8.1% in the catgut group (p less than 0.001). The period of hospitalization was reduced on an average by 2 days when using silk (p less than 0.001).

Cimethidine pre-anesthetic. A prophylactic method against Mendelson's syndrome in cesarean section.

Twenty patients undergoing cesarean section received cimethidine 400 mg intramuscularly as pre-anesthetic approximately 70 minutes prior to gastric aspiration. The average pH was 5.05, as against 2.97 in the control group (p less than 0.01). No significant reduction in the aspirated volumes was observed. In the cimethidine group the proportion of patients at risk of developing Mendelson's syndrome (pH less than 2.5 and volume greater than 25 ml) was significantly reduced, viz. 5% as against 42% in the control group (P = 0.014). No perinatal effects attributable to cimethidine was observed in the infants. Hence, cimethidine is a safe and useful pre-anesthetic for patients undergoing cesarean section, irrespective of indication and, consequently, much to be preferred to oral antacids.

Infantile hypertrophic pyloric stenosis and subsequent ulcer dyspepsia. A follow-up study of medically and surgically treated patients.

Infantile hypertrophic pyloric stenosis was treated in 324 cases in 1950-1966. At follow-up 19-35 years later, 296 of the patients could be traced, and 284 replied to a questionnaire concerning ulcer dyspepsia. Among the 80 patients who had been medically treated for pyloric stenosis, the prevalence of ulcer dyspepsia was 13.8%, and in the 204 surgically treated patients it was 9.3%. The difference was not statistically significant.
