Local anesthesia by peribulbar block for cataract extraction in an eye relief camp. A double-masked, randomized controlled trial.

OBJECTIVE: To test the hypothesis that the median scores for globe anesthesia are not significantly different for patients receiving local anesthesia (LA) by peribulbar block (PB) than for those receiving retrobulbar block (RB) for cataract surgery. DESIGN: Double-masked, randomized controlled trial. SETTING: An eye camp in Bhetwa, India, base hospital was King George's Medical College, Lucknow. (Eye camps are temporary set-ups used for cataract surgery throughout rural India.) Study carried out over a 2-day period. PATIENTS: Out of 125 patients eligible for intracapsular cataract extract on under LA, 122 agreed to enter the trial, and were randomly allocated to 2 groups just before the operation. The groups were equal in size and similar in composition in terms of patient age and sex. INTERVENTION: PB or RB infiltrated with 5 mL of the same anesthetic at the same site but with a different needle size and direction. MAIN OUTCOME MEASURES: Globe anesthesia (primary outcome), globe akinesia, lid akinesia, pupillary dilatation, and hypotony were scored separately on a 4-point scale during surgery by a masked surgeon. During infiltration, surgery, and the 1st 30 minutes after surgery, pain was scored by patients and recorded by an interviewer. RESULTS: Median scores for globe anesthesia were 4.0 in both groups, and the Mann-Whitney test revealed no difference in the medians of these scores (P = 0.6). There was no difference in scores on other outcomes measured, except lid akinesia, which was better with PB. Subjective pain scores were significantly higher with RB. The surgeon's guess about the type of LA administered was correct only for 58% of patients. CONCLUSION: PB is no different from RB in terms of producing globe anesthesia when used for cataract surgery at eye camps.

Congenital bilateral intermaxillary bony fusion.

Congenital fusion of maxillary and mandibular alveolar margins is extremely rare. Bony fusion between the jaws is still more uncommon. Only eight patients with bony fusion have been described in the literature to date, of whom only three had bilateral bony fusion. We present here a patient with very extensive bilateral bony fusion of the jaws, who underwent surgery with excellent immediate postoperative results. Details of the surgical management of this rare and difficult problem in a neonate with poor general condition are described.

Primary reconstruction of major human bite wounds of the face.

Primary reconstruction of 36 major human bite wounds of the face without clinical infection has been carried out successfully as late as the fourth day after the initial injury. Primary healing was achieved in all patients. The postoperative period was free from major infection in all patients except one, including the latecomers. Extensive bacteriologic studies reveal that the infection in human bite wounds occurs secondarily as invasion to devitalized tissue. We therefore consider that debridement of wound edges to eliminate the crushed devitalized tissue is the key to success.

Repair of bilateral cleft lip over prominent premaxilla.

Our experience of 25 cases of Millard's repair for bilateral cleft lip is described. We close the alveolus and anterior palate at the same time. The technique is applicable even in the presence of a prominent premaxilla with no previous oral orthopaedics of lip adhesion. The surgical correction of a bilateral cleft lip and palate is completed in two operative procedures. We show that good aesthetic and functional results were achieved.
