post-operative nausea 

 

Post-operative nausea or vomiting affects 25-30% of the population after receiving general anesthesia. Vomiting is not only extremely distressing to the patient, but it can also be associated with major complications and might endanger surgical outcomes after certain procedures. Out-patient procedures can turn into overnight admissions because of uncontrolled post-operative nausea and vomiting. 

ascents has created Nausea Relief No. 44 a blend of cardamom, ginger, spearmint and fennel to provide a quick relief from nausea. Numerous studies have examined the effects of aromatherapy as a treatment:

 

 

Hunt et al. conducted a randomized-trial of aromatherapy with patients who reported nausea in the postanesthesia care unit. Patients who complained of nausea received a gauze pad saturated with a randomly chosen aromatherapy agent and were told to inhale deeply 3 times; nausea was then measured again in 5 minutes. The change in nausea levels was significant concluding that aromatherapy would be effective as a treatment, and is a promising inexpensive, noninvasive treatment. Aromatherapy as Treatment for Post-Operative Nausea


Anderson et al. study the effect of aromatherapy on 33 surgery patients who complained of nausea in the PACU. Patients indicated the severity and then received randomized aromatherapy by inhaling vapors from scented gauze pads. Nausea levels were tested again 2 and 5 minutes later. Overall nausea scores decreased, and patients were satisfied overll with postoperative nausea management. Aromatherapy effectively reduced the perceived severity of postoperative nausea. Aromatherapy with Peppermint


Lane et al. examined the effect of peppermint spirits in postoperative nausea in women following a C-section. 35 women complaining of postoperative nausea were assessed and administered the assigned intervention, and then reassessed 2 and 5 minutes after. Participants in all three intervention groups had similar baseline levels; however when tested 2 and 5 minutes after, the nausea levels of participants in the peppermint spirits groups were significantly lower than those of participants in the other 2 groups. Peppermint may be a useful adjunct in the treatment of postoperative nausea. Peppermint Aromatherapy on Nausea
