A multimodal approach to postcesarean analgesia, using subarachnoid bupivacaine, fentanyl, morphine 100 microg, and clonidine 60 microg, improves pain relief compared with morphine 100 microg or clonidine 150 microg alone, but increases intraoperative sedation and may increase perioperative vomiting.

The aim of this study was to document the level of pain and functionality in the 12 months following orthopedic surgery and identify if high pain levels following discharge were associated with pain persisting at 12 months.An observational prospective cohort study was undertaken, following 87 patients (mean age 62.4 years [18–92]; 47.1% male) who required orthopedic surgery at the Royal Hobart Hospital, Australia. Following an initial survey, patients were telephoned at 10 days, 6 weeks, 3 months, and 12 months after discharge.Postdischarge pain levels were high with 97.4% of patients suffering pain at 10 days, 81.2% at 6 weeks and 79.5% at 3 months. Pain affected the ability to undertake activities of daily living (ADLs) for 32.7% and 20.0% of patients at 10 days and 6 weeks, respectively. Twelve months after discharge, 65.5% of patients reported pain persisting at the surgical site, with 29.9% of all patients suffering moderate–severe incidental pain; and nearly one quarter of patients reported pain affected their sleep or ADLs. Average pain levels rated as moderate–severe at 10 days (P = 0.01) and 6 weeks (P = 0.02) and pain of neuropathic origin at 3 months (30.2% vs 10.3% P = 0.03) and 12 months (30.4% vs 4.9% P = 0.01) were associated with persistent pain at 12 months.Pain in the period following discharge from hospital is significant and undermanaged. Previous studies has shown that that acute pain, particularly in the first 48 hours following surgery is a predictor for long-term pain after surgery. This study adds to the current literature by showing that pain in the subacute period, following discharge from hospital is also associated with the pain persisting at 12 months. These findings have important implications for improving quality of life as well as potentially preventing persistent pain with increased follow-up and more intensive management of post-discharge pain.

The addition of clonidine to epidural bupivacaine and fentanyl for PCEA in labor improved analgesia, reduced the supplementation rate, and reduced shivering. Increased sedation and lower BP were not clinically important.

We performed a prospective, randomized study in 55 ASA 1 to 3 women undergoing elective gynaecological surgery followed by postoperative epidural analgesia. We compared the incidence of bacterial colonization at the epidural exit site following catheter removal between a control group and an experimental group who received a chlorhexidine impregnated dressing (Biopatch, Johnson and Johnson, Arlington, TX, U.S.A.). Positive culture results were found in 11 of 27 (40.1%) patients in the control group compared with one of 29 (3.4%) patients whose epidural catheters were dressed with the Biopatch. We concluded that the Biopatch was effective in reducing bacterial colonization of the epidural catheter exit site.

This analysis supports previous research suggesting that epidural analgesia is not a significant risk factor for persisting post-partum back pain, headache or migraine.

SummaryWe report a case of low thoracic epidural and general anaesthesia in a patient receiving moclobemide, a new selective inhibitor ofmonoamine oxidase A . Intra-operative hypotension was initiaI1.v treated with phenylephrine and then with ephedrine. The short half-life of moclobemide and its modest interaction with direct and indirect acting sympathomimetic drugs permit the use of epidural anaesthesia, since any associated hypotension can be safely treated.

This study highlights the need for further research to investigate whether more intensive pain management in the post-discharge period following sternotomy as well as the early identification of patients with neuropathic pain symptoms can reduce the incidence of persistent post-operative pain at 12 months.

Difficult epidural insertion is not associated with an increased risk of needle contamination and is therefore an unlikely source of epidural infection.
