Randomized Controlled Trial Comparative Study Clinical Trial
Nalbuphine for obstetric analgesia. A comparison of nalbuphine with pethidine for pain relief in labour when administered by patient-controlled analgesia (PCA).
A double-blind, randomised study of 60 patients who received intravenous increments of nalbuphine 3 mg or pethidine 15 mg by patient-controlled analgesia during the first stage of labour, was carried out. Pain intensity, sedation, uterine contractions, maternal cardioventilatory variables and fetal heart rate were recorded as well as any side effects. ⋯ Group mean values of pain scores of nalbuphine-medicated primiparous women were statistically significantly lower than those of pethidine-medicated patients (p less than 0.01). Other assessments did not demonstrate a statistical significance between the two groups.

Case Reports
Brachial plexus block. Unilateral thoraco-abdominal blockade following the supraclavicular approach.
A supraclavicular brachial plexus block was performed which resulted in unilateral sensory and motor blockade of the thoracic and abdominal walls. General anaesthesia was therefore used and postoperatively it was noticed that analgesia of the upper limb had developed. It is likely that the blockade resulted from an intrapleural injection of local anaesthetic.

Tracheal intubation may be hindered by difficulty in insertion of the laryngoscope blade into the patient's mouth because the handle impinges on the patient's chest or on the hand of an assistant applying cricoid pressure. An adaptor is described which modifies the standard Penlon laryngoscope to enable lateral swivelling of the handle, thus avoiding the obstruction.
