硬膜外高渗氯化钠溶液术后镇痛的临床双盲研究

为观察高渗盐水硬膜外注射术后镇痛效果,用双盲法对60例病人进行了研究。生理盐水对照级术后镇痛优良率为3.33％,镇痛有效率为10％,均需用镇痛药;高渗盐水组术后镇痛优良率为86.67％,有效率为96.67％,很少使用镇痛药。两组差别显著(P<0.05,P<0.01)。对其他感觉和运动功能无明显影响。高渗盐水组与吗啡组比较镇痛效果相同(P>0.05),副作用少(P<0.01)。说明硬膜外高渗氯化钠溶液是一种安全有效的镇痛方法,有较高推广应用价值。     

Articular ossification after malignant neurolepsis. A case of schizophrenia treated with phenothiazines

Following administration of phenothiazines for schizophrenia, a 25-year-old patient developed a malignant neuroleptic syndrome followed by bilateral periarticular ossification of the knees, with severely limited motion. Two years later, the patient regained useful motion after bilateral excision of the ossified tissue and intensive physiotherapy. No recurrence of ossification was observed 3 years after operation, and the patient has maintained almost normal motion.     

Treatment of ulcerative colitis by traditional Chinese medicine and dynamic study of immune functions

The effect of the traditional Chinese medicinal herbs enema and enteric-coated capsules in the treatment of ulcerative colitis (UC) were compared in 260 cases. The immune complexes and the dynamic change of autoantibodies were monitored in 28 out of the 260 cases before and after treatment. The following results were observed. (1) There was no significant difference in the total effective rate between the enema group and the oral capsule group (93.3% and 87.5% respectively), but the recovery rates of purulent hemafecia, mucusfecia and erosion accompanying colitis, etc. in the former group were higher than those in the latter (P less than 0.01). (2) The circulating immune complexes were found 43 times above the normal range in 17 cases with positive rate 60.7%, and tended to decrease as the condition became better after treatment. Antinuclear antibodies were determined by the indirect fluorescent immune method and the indirect enzyme labelling method and the positive rates were 53.6% and 64.7% respectively, both being much higher than those in the controls (P less than 0.01).     

Intrapartum fetal heart rate patterns and neonatal intraventricular hemorrhage

A goal for the obstetrician and neonatologist is to screen for risk factors associated with intraventricular hemorrhage (IVH) in the low-birthweight infant. Perinatal events that lead to neonatal metabolic and cardiovascular derangements seem to provoke IVH, and conflicting reports have implicated labor as being contributory. A fetal heart rate (FHR) abnormality during premature labor may be a predictor of subsequent neonatal IVH. For this reason, 5 years of FHR tracings at two university medical centers were reviewed for inborn infants who were delivered after premature labor and weighed less than or equal to 2000 gm. Sixty-four infants developed IVH, but pre-existing labor with a discernible FHR pattern was recorded in only 38 (59%) cases. Interpretations were reassuring in 17 (45%) cases, suspicious in 7 (18%) cases, and ominous in 14 (37%) cases. This proportion of FHR patterns was not significantly different from a matched group of premature infants without IVH during the same period. Interpretations of intrapartum FHR patterns of low-birthweight infants are limited, especially before 30 weeks gestation, and not useful in predicting neonatal IVH.
