Sixty-eight deaths during pregnancy, parturition and puerperium were recorded in Sweden during the years 1971-80, giving a maternal mortality of 6.6 per 100,000 live births. The figures for abdominal delivery and vaginal were 45.0 and 2.5 per 100,000 live births respectively. ⋯ Age and parity are highly important risk factors. Presumed avoidable factors were identified in 19% of the cases. 9% of the deaths were related to unwanted pregnancy.

Randomized Controlled Trial Clinical TrialEffect of intraperitoneal instillation of 32% dextran 70 on postoperative adhesion formation after tubal surgery.
The intraperitoneal instillation of 32% dextran 70 (HyskonR, Pharmacia AB, Sweden) has previously been reported to prevent the formation of postoperative adhesions. Against this background, the present study was undertaken to evaluate the efficacy of HyskonR in counteracting peritoneal adhesions following tubal microsurgery. 105 infertile women were operated upon in a prospective, randomized, controlled, double-blind, multicenter study. ⋯ The extent of adhesions in the Hyskon group was not lesser than in the saline group, however. The pregnancy rates in the two groups were also similar.

Randomized Controlled Trial Comparative Study Clinical TrialAnalgesia and maternal side effects of pudendal block at delivery. A comparison of three local anesthetics.
In a randomized double-blind study, 1048 women received pudendal block (PDB) at vaginal delivery, using three different local anesthetics: mepivacaine 1% plain, mepivacaine 1% with epinephrine, and bupivacaine 0.25% plain. The PDB was given transvaginally in doses of 8 ml X 2. Mepivacaine - epinephrine was found to be more effective than the other local anesthetics. ⋯ Inhibition of labor was slightly more pronounced with mepivacaine - epinephrine. The different durations of the local anesthetics did not affect the analgetic effect in clinical use. It is concluded that as the adverse effects on labor are quite common, PDB should not be given as a routine before delivery, but may be offered liberally when pain in the pudendal area is a main part of the pain of childbirth.

Comparative Study Clinical TrialRelief of primary dysmenorrhea by transcutaneous electrical nerve stimulation.
In this study we describe the use of high-frequency transcutaneous electrical nerve stimulation (TENS) (100 Hz) and low-frequency TENS (lf-TENS) (2 Hz trains) as compared with placebo-TENS (p-TENS) in a group of 21 patients suffering from primary dysmenorrhea. Naloxone, a relatively pure opiate antagonist, was an additional test administered to 6 volunteer patients who had experienced an alleviation of pain with TENS. ⋯ During lf-TENS or p-TENS, only 7 and 5 patients, respectively, obtained pain relief exceeding 50%. In 4 out of 6 volunteer patients, the relief of pain obtained with lf-TENS was counteracted by naloxone, whereas the relief experienced with hf-TENS in the same patients was, in general, unaffected by naloxone.

Mode of delivery in the low birth weight fetus. Delivery by cesarean section independent of fetal lie versus vaginal delivery in vertex presentation. A study with long-term follow-up.
In a paired controlled multicenter study of patients in preterm labor of unknown etiology without additional maternal or fetal complications, 59 low birth weight infants in vertex presentation born vaginally were compared with 59 infants delivered by cesarean section. In the early postpartum period, hypothermia and acidosis occurred more often in the vaginal delivery group. ⋯ At follow-up until 18-24 months of age the rate of cerebral palsy did not differ between the groups, whereas the rate of psychomotor retardation was significantly higher in the vaginal delivery group (p less than 0.05). The difference in percentage of total outcome, i.e. sum of mortality and neurodevelopmental sequelae, being 20.3% in the vaginal delivery group versus 8.5% in the cesarean section group, fails to reach a statistical significance, but the results suggest that for the low birth weight infants, vaginal delivery may be more hazardous than abdominal delivery.
