  ABSTRACT: To compare caudal and penile block for post-operative analgesia in children undergoing circumcision with respect to efficacy, complication rates, and parental satisfaction. The study population consisted of 100 ASA 1 and 2 boys aged 3 to 8 years who were undergoing circumcision for religious reasons. In all participants, inhalation anesthesia was administered with oxygen : nitrous oxide (1 : 2) and halothane. The participants were allocated randomly into two groups of 50 children each. Group 1 received penile block and Group 2 caudal block. The penile block was achieved by injecting bupivacaine into the two compartments of the subpubic space, with an additional ventral infiltration of a small volume of bupivacaine along the raphe of the penis. For caudal block, 1 ml.kg(-1) body weight of 0.25% bupivacaine was administered. Penile block shortened the induction-incision time and enabled earlier discharge home compared with caudal block. One patient undergoing penile block and nine patients undergoing caudal block vomited. Penile and caudal block are equally effective for postcircumcision analgesia and neither is associated with serious complications. Anesthesiologist preference should be the deciding factor in choosing one technique over the other.

  ABSTRACT: To evaluate the efficacy and complications of immediate preoperative reduction of arterial blood pressure (BP) in patients with well-controlled hypertension but with diastolic blood pressure (DBP) between 110 and 130 mmHg on arrival at the operating room (OR). Prospective, randomized, large-sample study. University-affiliated, 550-bed community hospital. 989 patients with well-controlled hypertension, who were scheduled for surgery, and who had no previous myocardial infarction, unstable or severe angina pectoris, renal failure, pregnancy induced hypertension, left ventricular hypertrophy, previous coronary revascularization, aortic stenosis, preoperative dysrhythmias, conduction defects, or stroke. Patients with DBP between 110 and 130 mmHg were randomly allocated to two groups: 400 patients in the control group and 589 patients serving as the study group. The control group had their surgery postponed and they remained in hospital for BP control, and the study patients received 10 mg of nifedipine intranasally delivered. The patients were observed for cardiovascular and neurological complications during the intraoperative period and over the first three postoperative days. The two groups were similar in age, gender, type of surgery, duration of anesthesia, and intraoperative fluid administration. There were no statistically significant differences in postoperative complications. The hospitalization time was considerable shorter in the study group than in the control group. Immediate preoperative reduction of DBP with intranasal nifedipine is safe in patients with well-controlled arterial hypertension but they presented with severe to very severe hypertension for patients in the OR. We were able to avoid unnecessary surgery postponement and attendant costs.
