Although Drs. Manahan et al.1 correctly identify continuous propofol infusion as a preferred approach to prevent postoperative nausea and vomiting, several errors appear in their otherwise fine article. Table 1 mistakenly states as an Apfel postoperative nausea and vomiting risk factor “active smokers,” whereas the text correctly states “nonsmokers.”
The authors claim that ketamine should be avoided.2,3 Propofol-ketamine anesthesia4 has been subsequently cited by more than 175 later authors including Apfel, who cited it in Miller’s Anesthesia, the most prestigious textbook in the field.5,6 The published 0.6 percent postoperative nausea and vomiting rate is remarkable because all patients received before injection 50 mg of intravenous ketamine, were Apfel-defined as high risk, and yet none received antiemetic medication. Apfel’s postoperative nausea and vomiting chapter in Miller also states, “As long as emetogenic agents are part of the anesthetic regimen, the use of anti-emetics is of limited utility.”
The authors are correct when stating, “To control postoperative nausea and vomiting, the surgeon and anesthesiologist must work in concert.” Brain-monitored, propofol-ketamine anesthesia with local analgesia is simple to learn. Teaching cooperation is not. These references may help the authors emulate my 25-year success essentially eliminating postoperative nausea and vomiting.7–10
The use of the real-time electromyographic signal of the BIS (Medtronic, Minneapolis, Minn.) brain monitor clarifies the issue of “too light” versus “more local” in a dispassionate, numerically reproducible manner. With propofol titrated to BIS between 60 & 75 with baseline electromyogram (EMG), the patient is asleep and amnestic; patient movement without EMG activity is an indication for more local anesthetic in the immediate area of dissection.11 Vasoconstriction does not equal adequate analgesia. Elimination of movement will occur 98 percent of the time.
