[Potentiation of local anesthesia in endonasal surgery]

An original method of buccal administration of the drugs (by means of chewing gum) was tried in 30 patients aged 18-33 years. The drugs (ketrodol--0.5 mg/kg, diazepam--0.15 mg/kg, clofelin--1 microg/kg) were used to potentiate local anesthesia in operation--submucosal resection of the nasal septum under novocain solution anesthesia. Control 15 patients were operated under local anesthesia with morphine premedication (dose 10 mg). Adequacy of anesthesia was assessed by parameters of central and peripheral hemodynamics. Local anesthesia with morphine significantly activated sympathoadrenal system. Hyperdynamia was secured at the expense of accelerated cardiac rhythm with relatively low myocardial performance. Premedication with the chewing gum allowed to avoid pressor responses to the trauma in moderate hyperdynamia with adequate cardiac performance and minimal shifts in myocardial contractility.
