What is PONV medical term?
Postoperative nausea and vomiting (PONV) is a patient-important outcome; patients often rate PONV as worse than postoperative pain [1].
How do you treat PONV?
Patients at moderate to high risk for PONV benefit from the administration of a prophylactic antiemetic agent that blocks one or more of these receptors. Effective agents include transdermal scopolamine, prochlorperazine, promethazine, droperidol, ondansetron, dolasetron, granisetron, and dexamethasone.
How can PONV be prevented?
Using combinations of antiemetics may be the most effective method of preventing PONV for high-risk patients. Dexamethasone plus a 5-HT3 receptor antagonist is an effective combination. This combination was superior to placebo in preventing early and late nausea and vomiting.
What is a PONV score?
PONV was defined as nausea or vomiting within 24 h of surgery. Risk scores to estimate the probability of PONV were obtained by fitting logistic regression models. Simplified risk scores were constructed based on the number of risk factors that were found significant in the logistic regression analyses.
What is Dizinil medication used for?
Diznil 25mg Tablet belongs to a class of medicines known as antihistamines. It is used to treat motion sickness (nausea due to motion, especially while traveling in a moving vehicle), vertigo (spinning sensation or dizziness), or Meniere’s disease (problems with balance).
Why do people get PONV?
PONV results from patient, surgical, and anesthetic factors. Surgical factors that confer increased risk for PONV include procedures of increased length and gynecological, abdominal, laparoscopic and ENT procedures, and strabismus procedures in children.
How common is PONV?
PONV is one of the most common causes of patient dissatisfaction after anaesthesia, with reported incidences of 30% in all post-surgical patients and up to 80% in high-risk patients. In addition, PONV is regularly rated in preoperative surveys, as the anaesthesia outcome the patient would most like to avoid.
What is are the risk factors for PONV in the patient?
Female gender is the strongest patient specific predictor of PONV, followed by history of PONV or motion sickness, non-smoking status, and younger age. Anesthesia related factors include the use of volatile anesthetics, duration of anesthesia, perioperative opioid use, and use of nitrous oxide.
What causes nausea 3 days after surgery?
Experts estimate that about one in every three patients undergoing surgery requiring anesthesia will experience nausea in the hours or days following the operation. Much of the blame for this nausea lies in the type of anesthesia or pain relievers used, with opioid drugs like morphine a major culprit.Rab. II 21, 1425 AH

Why are females at higher risk of PONV?
Factors affecting PONV are patient characteristics, surgical procedure, anesthetic technique, and postoperative care. Female patients have 1.5-3 times greater incidence of PONV than males, due to increased plasma progesterone levels during their menstrual cycles.
Which is the best drug for PONV prophylaxis?
PONV prophylaxis is administered to patients with medium and high risks based on this scoring system. Newer drugs such as neurokinin-1 receptor antagonist (aprepitant) are used along with serotonin (5-hydroxytryptamine subtype 3) receptor antagonist, corticosteroids, anticholinergics, antihistaminics, and butyrophenones for PONV prophylaxis.
Are there any guidelines for the management of PONV?
Several guidelines, which have been published since, are either limited to a specific populations713or do not address all aspects of PONV management. The current guideline was developed based on a systematic review of the literature published up through September 2019. This includes recent studies of newer pharmacological agents such as the
How is PONV related to preoperative anesthesia factors?
PONV is influenced by multiple factors which are related to the patient, surgery, and pre-, intra-, and post-operative anesthesia factors. The risk of PONV can be assessed using a scoring system such as Apfel simplified scoring system which is based on four independent risk predictors.
What kind of surgery increases the risk of PONV?
Type of surgery: Cholecystectomy and gynecological and laparoscopic surgeries are associated with high incidence of PONV Duration of surgery: Longer duration surgeries are associated with increased incidence of PONV. Increasing operative duration by 30 min may increase the risk of PONV by 60%.
