We investigated the incidence of and risk factors for persistent pain after caesarean delivery. Over a 12-month period, women having caesarean delivery were recruited prospectively at an Australian tertiary referral centre. Demographic, anaesthetic and surgical data were collected and at 24 hour follow-up, women were assessed for immediate postoperative pain and preoperative expectations of pain. ⋯ Persistent pain, usually of a mild nature, is reported by some women two months after their caesarean delivery, but by 12 months less than 1% of women had pain requiring analgesia or affecting mood or sleep. All declined a pain clinic review. Clinicians and patients can be reassured that caesarean delivery is unlikely to lead to severe persistent pain in the long-term.

Randomized Controlled TrialEffect of alkalinisation of lignocaine for propofol injection pain: a prospective, randomised, double-blind study.
The aim of this study was to determine whether pretreatment with alkalinised lignocaine reduced the incidence and severity of pain during propofol injection. This prospective, randomised, double-blind study included 300 adult, American Society of Anesthesiologists physcial status I to II patients undergoing elective surgery. Patients were randomly allocated to one of three groups: Group L received 0.05 ml/kg of 1% lignocaine (5 ml normal saline + 5 ml 2% lignocaine), Group A received 0.05 ml/kg alkalinised lignocaine (5 ml 2% lignocaine + 1 ml 8.4% NaHCO3 + 4 ml normal saline), and Group S, the control group, was given the same amount of normal saline (NaCl 0.9%). ⋯ In addition, the pain score and the incidence of pain were found to be significantly different between Group L and Group S (P <0.001). The incidence of moderate and severe pain were greater in Group S when compared with groups A and L (P <0.001). Intravenous pretreatment with alkalinised lignocaine appears to be effective in reducing the pain during propofol injection.
