Study summary

Postoperative nausea and vomiting (PONV) is a surgical complication defined as any nausea, and vomiting with in the first 24-48 hours after surgery in inpatients. Nausea is an unpleasant feeling or desire to vomit without expulsive muscular movement, while vomiting is a forceful expulsion or reflux of the gastric contents through the mouth. Postoperative nausea and vomiting is one of the most common complication associated anesthesia and surgery. It is considered the most common cause of morbidity, and it has significant effects on patient satisfaction. In spite of recent development of anesthesia and surgical techniques, the incidence of PONV remains high. This common anesthetic and surgical side effect has been reported to increase patient dissatisfaction and can be just as distressing to patients as postoperative pain is.

Read the detailed description

Postoperative nausea and vomiting is caused by multiple factors; patient related, anesthesia and surgery related risk factors have been identified. Patient related factors include female gender post-puberty, nonsmoking status, history of PONV or motion sickness, and childhood after infancy and younger adulthood. Use of volatile anesthetics, nitrous oxide, large-dose neostigmine, or intraoperative or postoperative opioids are factors related to anesthesia, while the type of procedures like gynecologic, ophthalmological, ontological, thyroid surgery laparoscopic, abdominal surgery and duration of the procedure are some of surgery related risk factors.

The incidence of PONV for over multiple individual studies conducted around the world, has been estimated to be 25% to 30% and up to 80% in high risk groups. The incidence of PONV is estimated to range from 20%-36%.

Post-operative nausea and vomiting imposes multiple impacts on patients. The main one being a decrease satisfaction, but more importantly it leads to dehydration, electrolyte imbalance, aspiration of gastric secretions, esophageal rupture, bleeding, increased morbidity, and delayed discharge from hospital.

The study aimed to assess the incidence and associated factors of post-operative nausea and vomiting, which is believed to be a main contributing factor to dissatisfaction and delayed recovery seen in our country. The study was done from February to April 2022 in patients undergoing elective surgery at Dessie comprehensive specialized hospital, Ethiopia.
