Some of the topics which have generated particular interest in obstetric anesthesia recently include the effects of epidural anesthesia on the progress of labor, the efficacy of volume preloading prior to spinal anesthesia for cesarean section, and the use of intraspinal opioids and of alpha-2 adrenergic agonists for labor analgesia.

Parturients' assessment of water blocks, pethidine, nitrous oxide, paracervical and epidural blocks in labour.
This prospective study evaluated the extent to which the analgesic procedures available resulted in efficient pain relief in 833 Finnish parturients. Their pain ratings were recorded according to their own assessment of pain intensity during labour before and after pain management and according to their total pain experience recalled on the third day after delivery. Only regional blocks significantly diminished pain scores during labour and a striking decrease in pain level (P < 0.0001) was maintained until the second stage by epidural analgesia (EDA) alone. ⋯ After delivery 60% of parturients in this group recalled labour pain as being very severe or intolerable. This was partly due to delays in receiving epidural blockade and partly due to the parturient's reticence in requesting analgesia. Pain relief was rated as excellent or good by 94% of the EDA group but by only 50% of the remaining patients.

Randomized Controlled Trial Comparative Study Clinical TrialPatient-controlled analgesia: a comparison with nurse-controlled intravenous opioid infusions.
Patient-controlled analgesia (PCA) with intravenous pethidine was compared with nurse-controlled pethidine infusions for pain relief in 200 patients after major abdominal or thoracic surgery. Pain, level of sedation, nausea and presence of other adverse effects, in addition to cumulative pethidine requirement, were measured for the first 24 hours after surgery. Both groups were similar for age, weight and type of surgery. ⋯ The frequency and severity of adverse effects was also similar. The cumulative pethidine dose administered to both groups was identical. It is concluded that nurse-controlled opioid infusions are as effective as PCA and may be used as an alternative to PCA where this is either unavailable or unsuitable.

Acute pain management in critically ill ICU patients is an area that needs increased attention. Modern techniques exist that can help speed recovery and reduce duration of ICU and, potentially, hospital stay. Application of contemporary knowledge in this area benefits both clinician and patient.

Decreased incidence of headache after accidental dural puncture in caesarean delivery patients receiving continuous postoperative intrathecal analgesia.
To examine the effects of prolonged (> 24 h) intrathecal catheterization with the use of postoperative analgesia on the incidence of post-dural puncture headache (PDPH), charts of 45 obstetric patients who had accidental dural puncture following attempts at epidural block were reviewed retrospectively. Three groups were identified: Group I (n = 15) patients had a dural puncture on the first attempt at epidural block, but successful epidural block on a repeated attempt; Group II (n = 17) patients had a dural puncture with immediate conversion to continuous spinal anaesthesia with catheterization lasting only for the duration of caesarean delivery; Group III (n = 13) patients had an immediate conversion to spinal anaesthesia and received post-caesarean section continuous intrathecal patient-controlled analgesia consisting of fentanyl 5 micrograms.ml-1 with bupivacaine 0.25 mg.ml-1 and epinephrine 2 micrograms.ml-1 with catheterization lasting > 24 h. No parturient in group III developed a PDPH. ⋯ Similarly, there was no difference between group I and II with regard to requests for a blood patch. Patients receiving continuous intrathecal analgesia had excellent pain relief, could easily ambulate and none complained of pruritus, nausea, vomiting, sensory loss or weakness. In conclusion, indwelling spinal catheterization > 24 h with continuous intrathecal analgesia following accidental dural puncture in parturients may for some patients be a suitable method for providing PDPH prophylaxis and postoperative analgesia.
