The duration of pain relief after penile block to boys undergoing circumcision.
Bupivacaine plain, 2.5 mg/ml, was used for a nerve block of the dorsal nerves of the penis. Satisfactory postoperative analgesia was obtained in 24 of 28 boys undergoing circumcision. Eighteen of the 24 boys with a successful nerve block did not require analgesics during the first 24 h postoperatively. All blocks were performed by the surgeon just before surgery.

Continuous axillary brachial plexus block--a clinical and anatomical study.
In order to decrease both the failure rate and inadvertent arterial puncture rate that may be associated with continuous axillary brachial plexus block, a new technique of insertion of the catheter in the axilla was studied in 52 patients and in 12 fresh cadavers. With the arm abducted, externally rotated, and flexed at the elbow, an 80-mm long catheter was inserted under the skin at a site located 40-mm below the axilla and medial to the biceps muscle. Injection of lidocaine and bupivacaine produced sensory and motor blockades of the median, radial, ulnar, and musculocutaneous nerves in 98% of the patients. ⋯ In the anatomical study, injection of dye and molding solutions showed that the tip of the catheter lay not in the perivascular sheath, but in a virtual cavity that was very superficial, under the skin, and surrounding the perivascular space. The technique used was safe and had a high success rate. It is particularly useful in patients undergoing long operations and in patients in whom pain would otherwise prevent postoperative physiotherapy of the upper arm.

Comparative StudyComparison of the effectiveness of etidocaine and lidocaine as local anesthetic agents during oral surgery.
In a double-blind study conducted in 112 patients undergoing removal of four impacted third molar teeth, etidocaine hydrochloride 1.5% solution with epinephrine 1:200,000 and lidocaine hydrochloride 2.0% solution with epinephrine 1:100,000 were used, one on each side of the face, to produce inferior alveolar nerve block, infiltration anesthesia of the maxillary tooth and hemostasis of the mucoperiosteum around each tooth. Surgically adequate anesthesia was rapidly produced by both agents but the duration of action of etidocaine was longer than that of lidocaine as reflected in more prolonged numbness of the lip and delayed onset of pain. Moreover, after etidocaine treatment fewer patients reported severe pain as the local anesthesia receded. No adverse local or systemic effects were observed in, or reported by, any of the patients.
