Abstract:

The study was conducted to assess the potential usefulness of general electroanesthesia in dentistry. Experimental subjects were rhesus macaque monkeys. Circuitry was designed and constructed to yield a waveform comprised of a high frequency 100 KHZ pulse train modulated by a low frequency 100 HZ pulse train. The modulated waveform was applied transcranially through saline-soaked cotton electrodes placed at nasion cathode and inion anode. The current was increased from an initial level of 10 ma peak to a maximum of 50 ma peak over a 20-minute induction period. Average values of the initial and final currents were 1.0 ma and 5.0 ma, respectively. Induction was accomplished with and without the use of chemical adjuncts. However, medication phencyclidine hydrochloride 0.5 mg per kg body weight prior to administration of the current appeared to alleviate discomfort elicited by the low frequency component of the waveform. Conventional restorative, endodontic and oral surgical procedures were accomplished readily at low current levels.
