Randomized Controlled Trial Comparative Study Clinical Trial
Dose response study of lidocaine 1% for spinal anaesthesia for lower limb and perineal surgery.
To compare the sensory and motor block produced by three different volumes of intrathecal lidocaine 1% and thereby determine the appropriate volume to administer for surgery of the lower limbs and perineum. ⋯ Four millilitres intrathecal lidocaine 1% is adequate for perineal surgery but for lower limb procedures, 6 ml is more appropriate as it consistently provides sensory analgesia above L1 dermatome and complete motor block. Eight ml gives an unnecessarily high block with higher incidence of hypotension.

Clinical Trial
Epidural analgesia in early labour blocks the stress response but uterine contractions remain unchanged.
To determine the effect of epidural analgesia on biochemical markers of stress, plasma oxytocin concentrations and frequency of uterine contractions during the first stage of labour. ⋯ The metabolic stress response to the pain of labour was attenuated by epidural analgesia. In contrast, plasma oxytocin concentration and frequency of uterine contractions were unaffected by the attenuation of metabolic stress response.

To determine the incidence, the reasons, and the predictive factors for unanticipated admission after ambulatory surgery. ⋯ Earlier operating time for certain surgical procedures, screening for proper support at home, and implementation of clinical pathways to deal aggressively with problems such as pain, nausea and vomiting should decrease the incidence of unanticipated admission.

To examine the reliability of low current electrical epidural stimulation to confirm epidural catheter placement. ⋯ This study establishes this test as a simple, objective and reliable technique for confirmation of epidural catheter placement.
