PONV

The frequency of post-tonsillectomy emesis is more frequent in pediatric patients than in adults.6 Dexamethasone has been reported to have prophylactic effect on PONV in patients undergoing tonsillectomy.7 The objective of the present study was to compare the effects of single intra-operative intravenous dose of dexamethasone versus control group on frequency of post operative nausea and vomiting and the need for rescue antiemetics in the first 24 hours in patients undergoing tonsillectomy/ adenotonsillectomy.

In their view, the evidence is strongest for acupuncture's effectiveness in preventing PONV. One recent research summary, including data on nearly 4,900 patients, concluded that treatment directed at one specific "acupoint" is as effective as conventional drug treatments in preventing PONV, with only minor side effects.

The incidence of PONV has remained high and has a major negative impact on patient satisfaction about the overall surgical experience.

There is some evidence that vestibular inputs modify the emetic response from other stimuli: a history of motion sickness is a risk factor for development of PINV, PONV and CINV.

Patients were checked or PONV three hours after endoscopic procedure.

Confirm homeostasis before attempting extubation, and ensure adequate prophylaxis for PONV. Continuous positive airway pressure (CPAP or BiPAP) rather than increased [FiO.sub.2] should be used postoperatively to improve oxygenation when signs of OSA are present.

Many patients, especially those who previously experienced previous PONV or are receiving cancer therapy treatments, may experience anticipatory nausea and vomiting.

An independent blinded observer assessed PONV during first 24 h following surgery using visual analogue scale (VAS) score (0 = no nausea, 10 = worst imaginable nausea or vomiting).

What remains unresolved is the use of droperidol in clinical situations, in which it is the preferred agent for PONV, including after cesarean section, and for HG.

A French study the same year observed QTc prolongation after IV bolus doses of droperidol (0.75 mg) and ondansetron (4 mg) for PONV shortly after surgery.

Conclusion: This clinical study indicates that when performing prolonged surgical procedures, late administration of ondansetron (within 30 minutes prior to completing the surgery) is significantly more effective in the prevention of late PONV than when administered prior to the induction of anesthesia.
