Ventricular arrhythmias after epinephrine injection in enflurane and in halothane anesthesia.
The use of subcutaneous epinephrine during anesthesia is a common clinical practice for providing surgical hemostasis. In studies with 100 patients given either enflurane or halothane, with or without subcutaneous epinephrine, the incidence of ventricular ectopy in patients receiving halothane without epinephrine was 3 percent, while in those given epinephrine with halothane, the incidence was 7 percent. Those who received enflurane alone had no ectopic beats, while ventricular ectopy with enflurane and epinephrine resulted in an incidence of 1 percent. The authors conclude that enflurane anesthesia with concomitant administration of subcutaneous epinephrine is safe, provided the safeguards previously established for use of epinephrine with halothane are observed.

A new single-position supine approach to sciatic-femoral nerve block.
To overcome the disadvantages of other methods, the authors have devised a procedure for below-the-knee operations, involving a new technic of sciatic-femoral nerve block. The technic has so far been successful without use of adjuvant agents in 90 percent of over 100 patients so handled.

Comparative StudyEffects of intraoperative PEEP on postoperative arterial oxygenation.
Previous studies have suggested that early postoperative hypozemia may be due to a reduction of functional residual capacity (FRC) during anesthesia and surgery. Positive end-expiratory pressure (PEEP) has been recommended as a means of maintaining FRC and improving arterial oxygenation. ⋯ Patients receiving PEEP maintained the highest mean Pao2 intraoperatively. However, the beneficial effect of intraoperative PEEP was not sustained in the recovery room, where all patients experienced the same degree of arterial hypoxemia.

Epidural blood patch (EBP) was performed for the treatment of severe postlumbar puncture cephalalgia in 118 young patients. Following the first EBP, 105 patients had relief of headache. Eleven of the 13 in whom it failed had a second EBP, with adequate relief in 10, giving an overall success of 97.5 percent. ⋯ Residual complications included backache and/or back stiffness in 22 patients and paresthesia in two. Two-year follow-up revealed 95 percent patient acceptance of the procedure. EBP was found to be a safe, effective method for treating severe postlumbar puncture cephalalgia, provided a proper diagnosis is made and there is no contraindication.
