To show the use of the short acting opioid remifentanil for labour analgesia when epidural analgesia is considered to be contraindicated. ⋯ Remifentanil PCIA combining low continuous background infusion and small bolus doses is an alternative when epidural analgesia in labour is contraindicated. Under careful anesthesia monitoring, the technique seems to be safe for both mother and baby, at least when delivery occurs at or near the normal term of pregnancy.

Randomized Controlled Trial Clinical Trial
Dexamethasone prophylaxis of nausea and vomiting after epidural morphine for post-Cesarean analgesia.
To determine the minimum effective dose of dexamethasone in preventing nausea and vomiting associated with epidural morphine for post-Cesarean analgesia. ⋯ Dexamethasone, 5 mg i.v., is suggested as the minimum effective dose in preventing nausea and vomiting associated with epidural morphine for post-Cesarean analgesia.

Randomized Controlled Trial Clinical Trial
Dextromethorphan attenuation of postoperative pain and primary and secondary thermal hyperalgesia.
To determine the effect of 90 mg dextromethorphan (DM) p.o. vs placebo 90 min preoperatively, on the immediate and delayed postoperative course. ⋯ Compared with placebo, DM enabled reduction of postoperative analgesics consumption, improved well-being, and reduced sedation, pain intensity and primary and secondary thermal hyperalgesia.

Veno-arterial and regional differences of the partial pressure in CO2 (deltaPCO2), may be used as index to evaluate the adequacy of the cardiac output to the oxygen consumption. To determine the incidence of elevated deltaPCO2 and its relationship with difficult separation from bypass (DSB) in patients undergoing cardiac surgery, we conducted a prospective observational cohort study. ⋯ Elevated deltaPCO2 is frequently observed during cardiac surgery and values obtained before bypass were associated with DSB. The deltaPCO2 gradients could be used as marker of the adequacy of tissue perfusion during cardiac surgery.
