Tattoos-ancient forms of permanent body ornamentation (body art) have today become popular fashion accessories worldwide. More than 50% of all tattoos are being done on women. In the recent years body tattooing in unconventional sites (e.g. lumbar and/or sacral area, lower abdomen, breast, and buttocks) has gained increasing popularity among young women (including in pregnancy). Although, the potential hazards of regional anesthesia in patients with lumbar tattoos remain controversial it may seem prudent to avoid a hollow needle insertion (possible tissue entrapment in its bore as the needle passes to the deeper structures) through a tattoo for neuraxial blocks. This author is not aware of any other review articles in English literature discussing implications, and complications of labor analgesia in parturients presenting with lumbar tattoos.
Epidural analgesia is considered by many to be the best method of pain relief after major surgery. It is used routinely in many thoracic surgery centres. Although effective, side-effects include hypotension, urinary retention, incomplete (or failed) block, and, in rare cases, paraplegia. Paravertebral block (PVB) is an alternative technique that may offer comparable analgesic effectiveness and a better side-effect profile. We undertook a systematic review and meta-analysis of all relevant randomized trials comparing PVB with epidural analgesia in thoracic surgery. Data were abstracted and verified by both authors. Studies were tested for heterogeneity, and meta-analyses were done with random effects or fixed effects models. Weighted mean difference (WMD) was used for numerical outcomes and odds ratio (OR) for dichotomous outcomes, both with 95% CI. We identified 10 trials that had enrolled 520 thoracic surgery patients. All of the trials were small (n<130) and none were blinded. There was no significant difference between PVB and epidural groups for pain scores at 4-8, 24 or 48 h, WMD 0.37 (95% CI: -0.5, 121), 0.05 (-0.6, 0.7), -0.04 (-0.4, 0.3), respectively. Pulmonary complications occurred less often with PVB, OR 0.36 (0.14, 0.92). Urinary retention, OR 0.23 (0.10, 0.51), nausea and vomiting, OR 0.47 (0.24, 0.53), and hypotension, OR 0.23 (0.11, 0.48), were less common with PVB. Rates of failed block were lower in the PVB group, OR 0.28 (0.2, 0.6). PVB and epidural analgesia provide comparable pain relief after thoracic surgery, but PVB has a better side-effect profile and is associated with a reduction in pulmonary complications. PVB can be recommended for major thoracic surgery.
BACKGROUND AND OBJECTIVE: We examined the efficacy of intraoperative propofol administration to prevent pruritus induced by epidural morphine. METHODS: Seventy patients ASA I-II undergoing combined epidural and general anaesthesia for hysterectomy were randomly assigned to two groups, Group P where anaesthesia was induced with propofol and fentanyl and maintained with propofol-nitrous oxide and Group S in which anaesthesia was induced with thiopental and fentanyl and maintained with sevoflurane-nitrous oxide. All patients received a ropivacaine epidural bolus with 3 mg morphine 1 h before the end of surgery. The incidence and severity of pruritus were evaluated every 4 h for the first 12 h postoperatively by blinded observers. RESULTS: The total incidence of pruritus was significantly higher (P = 0.024) in Group S (65.6%) compared to Group P (29%) between 4 and 8 h postoperatively. There were also significantly more patients (P = 0.03) reporting severe pruritus in Group S (22%) compared to Group P (0). CONCLUSION: Propofol-based general anaesthesia compared to thiopental-sevoflurane-based anaesthesia reduces the incidence and severity of pruritus induced by a single injection of 3 mg epidural morphine with ropivacaine.
