Randomized Controlled Trial Comparative Study
P6 acupressure increases tolerance to nauseogenic motion stimulation in women at high risk for PONV.
In a previous study we noticed that P6 acupressure decreased postoperative nausea and vomiting (PONV) more markedly after discharge. As motion sickness susceptibility is increased by, for example, opioids we hypothesized that P6 acu-pressure decreased PONV by decreasing motion sickness susceptibility. We studied time to nausea by a laboratory motion challenge in a group of volunteers, during P6 and placebo acupressure. ⋯ In females with a history of motion sickness P6 acu-pressure increased tolerance to experimental nauseogenic stimuli, and reduced the total number of symptoms reported.

Randomized Controlled Trial
Propofol ensures a more stable A-line ARX index than thiopental during intubation.
The A-line autoregressive modelling with exogenous input index (AAI) is a new method of assessing depth of anesthesia. We examined the effects of tracheal intubation on the AAI and hemodynamics during induction of anesthesia with propofol compared with thiopental in patients aged over 50 yr. ⋯ Our results, using the AAI to monitor anesthetic depth during induction and tracheal intubation, suggest that at equipotent doses propofol provided a more stable level of anesthesia than did thiopental.

Randomized Controlled Trial Comparative Study
[Thoracic epidural and intrathecal analgesia have similar effects on pain relief and respiratory function after thoracic surgery].
To compare in a prospective randomized trial the effects of thoracic epidural infusions of fentanyl (F) and bupivacaine (B) to intrathecal morphine (M) and sufentanil (S) on analgesia and respiratory function following thoracotomy. ⋯ This study shows that intrathecal M and S offer analgesia comparable to thoracic epidural infusion of B and F.
