Abstract:
This study was done for intrathecal adjuncts often are used to enhance small dose spinal bupivacaine anaesthesia. We designed this study to evaluate the postoperative analgesic efficacy and safety of intrathecal neostigmine. A randomized, double-blind prospective study was conducted in 90 healthy term pregnant patients scheduled to undergoing elective caesarean section using spinal anaesthesia. Women were administered 12.5 mg bupivacaine alone or with 75 microgram and 150 microgram of neostigmine as intrathecal drug. Parametric data were analyzed using ANOVA. Chi-square test was used to analyze the incidence data. Neostigmine significantly increased the duration sensory and motor block (p<0.05) and the time until for achieving discharge criteria. The addition of neostigmine produced dose-dependent nausea and vomiting and had no significant effect on haemodynamic or respiratory parameters. Addition of neostigmine to intrathecal bupivacaine extends the duration of postoperative analgesia with fewer side-effects without adverse effects on fetus following caesarean section.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
