A nation-wide survey of pain relief in childbirth in Hungary was carried out in 1993. Information was provided on 104 137 deliveries in 98 units. The frequencies of different methods of pain relief for vaginal delivery were as follows: systemic opiates in 7387 cases (8.3%), epidural analgesia in 4611 cases (5.2%) and inhalational analgesia (nitrous oxide) in 4470 cases (5%). ⋯ For 71 744 vaginal deliveries (80.5%) no pain relief was provided at all. For caesarean section (n = 13240) the rate of spinal or epidural anaesthesia was 36.7%. It was concluded that despite an increasing rate of pain relief in labour elsewhere, the numbers of epidurals are still rather low in Hungary.

Randomized Controlled Trial Clinical TrialA double-blind assessment of the analgesic sparing effect of intrathecal diamorphine (0.3 mg) with spinal anaesthesia for elective caesarean section.
In a randomized double-blind study, 40 healthy women undergoing elective caesarean section with spinal anaesthesia received either 0.3 mg diamorphine or saline with bupivacaine 0.5% in 8% dextrose. The study recorded time to the first morphine demand delivered by patient-controlled analgesia (PCA), and total morphine requirement over 24 h. In addition pain, sedation, and pruritus were assessed by non-graduated visual analogue scores (VAS). ⋯ The medians (interquartile ranges) were 5 (0, 36) mg vs 45 (26, 72) mg (P 0.0045, 95% confidence interval for the difference between the medians is 12 to 46 mg). In the diamorphine group, postoperative VAS for pain was significantly lower at 2 h and 3 h both at rest (P 0.0003, 0.003) and on moving (P 0.009, 0.002), at 8 h on moving (P 0.01), and at 12 and 24 h at rest (P 0.005, 0.029). Significantly more women suffered pruritus in the diamorphine group for the first 12 h after surgery (P 0.01).

Randomized Controlled Trial Clinical TrialIntrathecal labor analgesia: can we use the same mixture as is used epidurally?
In a randomized double-blind study, three groups of 25 term parturients received one of the following intrathecal drugs or combinations for relief of labor pain: sufentanil 7.5 microg (1.5 ml), sufentanil 5 microg + bupivacaine 1 mg (1.5 ml) or the combination bupivacaine 1.75 mg, sufentanil 1.05 microg and epinephrine 1.75 microg, that is 1.5 ml of our standard epidural mixture. After the intrathecal injection, patients received a peridural catheter for supplementation of analgesia. Onset and duration of the three regimens were similar. ⋯ More cardiotocographic changes were observed in the plain sufentanil group but this was not related to neonatal outcome. It was concluded that intrathecal injection of the standard epidural mixture offers effective and long-lasting analgesia. This may avoid side-effects and complications, manipulations of drugs with the risk for contamination, spilling of drugs and loss of time.

Factors involved in the incidence of post-dural puncture headache with the 25 gauge Whitacre needle for obstetric anesthesia.
Parturients have the greatest risk of postdural puncture headache. use of a pencil-point needle, such as the 25 gauge Whitacre, has been associated with a lower incidence of PDPH. This observational study of 1009 obstetrical patients assessed possible factors related to the incidence of PDPH and other complications associated with spinal anesthesia using the 25 gauge Whitacre needle. The independent variables included procedure, maternal position at insertion, ease of insertion, intraoperative i.v. analgesia supplementation, use of intrathecal narcotics, parity and type of local anesthetic. ⋯ Six patients (0.59%) required epidural blood patch. There were eight (0.8%) failed finals which were converted to general anesthesia. None of the factors evaluated were significant in predicting the occurrence of PDPH.
