ReviewHeadache after lumbar puncture: review of the epidural blood patch.
The incidence of accidental dural puncture during epidural block is 2.9%; headache follows in as many as 76.5% of these patients. Treatment by injection of autologous blood into the epidural space has gained wide acceptance since its introduction in 1960, though it is contraindicated by blood dyscrasias, anticoagulant therapy, bleeding, and localized infection. The procedure is done by slowly injecting 15 to 20 ml of blood into the same interspace, no sooner than 24 hours after the original puncture. Serious complications are rare.

Cardiopulmonary effects of the head-down tilt position in elderly postoperative patients: a prospective study.
We studied the use of the head-down tilt position (Trendelenburg) in elderly postoperative patients in the intensive care unit to determine its effect upon cardiac and pulmonary function. Twenty-two patients (mean age 68.4 years) were placed in a 12 degrees head-down tilt position for 15 minutes. ⋯ Because of the uncertain effect of the head-down tilt position upon cerebral blood flow, the routine use of this position is not recommended for the treatment of hypotension or during cardiopulmonary resuscitation. The results of this study, however, show that the cardiopulmonary effects are well tolerated if the position is required, as during central venous access procedures.

Penetrating trauma to the buttock is an injury with potential impact on multiple body systems. The purpose of this study was to review our experience with penetrating trauma to the buttock, to establish the frequency of system injury and related morbidity and mortality, and to make recommendations for the evaluation and management of these injuries. Among the 56 system injuries, soft tissue injuries predominated. ⋯ There were no deaths in this series. Morbidity consisted of nerve injury/defect in three patients, stroke in one patient, and impotence in one. An understanding of the systems at risk in penetrating buttock trauma is necessary for prompt multisystem work-up.

Postoperative ketamine analgesia in children: efficacy and safety after halothane anesthesia.
This study was done to investigate the effectiveness and safety of ketamine analgesia after halothane anesthesia for surgery in children. After completion of a surgical procedure, ten children had ketamine (1 mg/kg) injected intravenously during maintenance of anesthesia with 1% halothane in a 60:40 nitrous oxide-oxygen mixture. Cardiovascular parameters measured with noninvasive oscillometry and transthoracic impedance plethysmography remained unchanged after administration of ketamine. ⋯ When ketamine and halothane are administered in combination, careful restriction of dosages of these agents is recommended. Interaction of higher doses of ketamine and halothane has been reported to produce hypotension and bradycardia, which can be avoided with use of subdissociative, analgesic doses of ketamine during light halothane maintenance before emergence. After halothane anesthesia in healthy children, ketamine may be considered a suitable alternative to narcotics for postoperative analgesia.
