Randomized Controlled Trial Comparative Study Clinical TrialCaudal or dorsal nerve block? A comparison of two local anaesthetic techniques for postoperative analgesia following day case circumcision.
Fifty boys presenting for day case circumcision were allocated randomly to receive either caudal analgesia or dorsal nerve block (DNB) to provide postoperative pain relief. Analgesia was assessed by a single, unbiased observer utilising a three-point scale. Subsequently, parents completed a simple questionnaire. ⋯ The incidence of vomiting was significantly lower in the DNB group (P less than 0.05). There was no significant difference in the duration of analgesia, although that produced in the DNB group tended to wane sooner. It is concluded that DNB provides satisfactory analgesia following circumcision and has specific advantages when compared with caudal analgesia.

Randomized Controlled Trial Comparative Study Clinical TrialAnalgesia and maternal side effects of pudendal block at delivery. A comparison of three local anesthetics.
In a randomized double-blind study, 1048 women received pudendal block (PDB) at vaginal delivery, using three different local anesthetics: mepivacaine 1% plain, mepivacaine 1% with epinephrine, and bupivacaine 0.25% plain. The PDB was given transvaginally in doses of 8 ml X 2. Mepivacaine - epinephrine was found to be more effective than the other local anesthetics. ⋯ Inhibition of labor was slightly more pronounced with mepivacaine - epinephrine. The different durations of the local anesthetics did not affect the analgetic effect in clinical use. It is concluded that as the adverse effects on labor are quite common, PDB should not be given as a routine before delivery, but may be offered liberally when pain in the pudendal area is a main part of the pain of childbirth.
