Review Meta Analysis
Short-term preoperative smoking cessation and postoperative complications: a systematic review and meta-analysis.
The literature was reviewed to determine the risks or benefits of short-term (less than four weeks) smoking cessation on postoperative complications and to derive the minimum duration of preoperative abstinence from smoking required to reduce such complications in adult surgical patients. ⋯ At least four weeks of abstinence from smoking reduces respiratory complications, and abstinence of at least three to four weeks reduces wound-healing complications. Short-term (less than four weeks) smoking cessation does not appear to increase or reduce the risk of postoperative respiratory complications.

Comparative Study
Remifentanil versus fentanyl for intravenous patient-controlled labour analgesia: an observational study.
We undertook a retrospective study to compare the analgesic efficacy and effects on neonatal outcome of administering either remifentanil or fentanyl intravenous patient-controlled analgesia (IVPCA) during labour. ⋯ Intravenous patient-controlled analgesia with either remifentanil or fentanyl provides a moderate degree of labour analgesia, whereas transient maternal oxygen desaturation is observed more commonly with remifentanil. Fentanyl is associated with a higher need for neonatal resuscitation.
