Comparison of plain with pH-adjusted bupivacaine with hyaluronidase for peribulbar block.

Fifty patients scheduled for cataract surgery under peribulbar block were randomised to receive either plain (pH 5.4) or pH-adjusted (pH 6.8 range 6.7-6.9) 0.75% bupivacaine. Hyaluronidase was added to both solutions prior to peribulbar block. The time of onset of akinesia of the globe and the need for supplementary injections were recorded by an independent observer. Patients who returned for surgery to the second eye received the alternative local anaesthetic solution for the second peribulbar block. The relative efficacy of the different anaesthetic solutions was compared in patients who underwent unilateral surgery (Group A, n = 50). In 12 patients (Group B) who underwent bilateral surgery, direct comparisons between eyes in the same patient were possible. In both groups of patients, eyes receiving peribulbar block with the pH-adjusted solution showed a shorter time to partial akinesia of the globe (P less than 0.05). However, there was no difference between the solutions in the time to complete akinesia of the globe, but the number of supplementary injections required for an effective block with the pH-adjusted solution was increased. Onset time to akinesia of the lateral and superior rectus muscles was shortened in patients receiving the pH-adjusted solution but there were minimal effects on the medial and inferior recti.

Alcohol, drugs, and adolescent sexual behavior.

In a 1990 Massachusetts-wide random digit-dial telephone survey of 16-19 year olds, 66% reported sexual intercourse of whom 64% had sex after drinking and 15% after other drug use. Thirty-seven percent always used condoms. Forty-nine percent were more likely to have sex if they and their partner had been drinking, and 17% used condoms less often after drinking. Fewer, 32%, said they would be more likely to have sex if they and their partner had used drugs, with 10% less likely to use condoms after drug use. Since so few adolescents consistently use condoms, the greatest risk for HIV, sexually transmitted diseases, and unwanted pregnancy is the increased likelihood of having sex after drinking or drug use, not the decreased likelihood of condom use after drinking and drug use.

Knowledge about HIV and behavioral risks of foreign-born Boston public school students.

In 1990, 3049 Boston public middle and high school students were surveyed anonymously in English, Spanish, Vietnamese, Chinese, French, or Haitian Creole. Significantly fewer immigrant students, 35% of those surveyed, knew the principal modes of human immunodeficiency virus transmission. Fewer immigrants reported having sexual intercourse (31% vs 53% of nonimmigrants), but among the sexually active only 38% always used condoms, and more immigrants reported intercourse with intravenous drug users (4% vs 1% of non-immigrants). AIDS education should be taught to immigrant students in their native languages.

Blood carbon dioxide tension changes during hysteroscopy.

During hysteroscopy the uterus may be distended with carbon dioxide (CO2), nitrous oxide (N2O), or Hyskon (a high molecular weight dextran). An initial study in 27 patients (group 1) using arterialized venous blood samples demonstrated rises in carbon dioxide tension (PCO2) when N2O was insufflated by using a laparoscopy insufflating device--a constant-pressure, variable-volume gas source. Cardiovascular collapse occurred in one patient in this group, most probably as a result of macropulmonary emboli of N2O. The rise in PCO2 is accounted for by an increase in physiologic dead space. In another 24 patients (group 2) the gaseous media were introduced by using a constant-volume, variable-pressure gas source; this resulted in minimal changes in arterial PCO2. The choice of whether a gaseous or liquid distending medium is used for hysteroscopy is governed by the state of the endometrium. If a gaseous medium is indicated, then CO2 is preferable to N2O and should be introduced with a constant-volume, variable-pressure gas source.

Sedation for outpatient conservative dentistry. A trial of pentazocine supplementation to diazepam and local analgesia techniques.

Pentazocine 30 mg. or 15 mg or a placebo, was administered randomly to forty-nine patients undergoing conservative dental treatment in combination with a local analgesic block and intravenous diazepam. Simple cardiorespiratory measurements were made throughout the treatment period. Patients in the 30 mg pentazocine group required some 6 mg diazepam less than the placebo (control) group (P less than 0.05). Patients receiving 15 mg pentazocine also required less diazepam compared to the control group, but this difference was not statistically significant. There were no significant differences between the three groups either in recovery times or the cardiorespiratory measurements.

Anaesthetic waste gas scavenging systems.

The Department of Health and Social Security has recently recommended that waste anaesthetic scavenging systems should be installed to reduce pollution in operating theatres. Three passive and two active systems were compared to see how effectively they reduced concentrations of halothane in the atmosphere. All five systems reduced halothane levels significantly, the combination of an active system and semiclosed circuitry being the most effective. All obvious leaks from equipment were controlled in this study, but normally such leaks contribute significantly to atmospheric pollution. Some of the benefits of a scavenging system may be lost if gases can still escape through leaks.
