For some procedures, you may receive medication that makes you sleepy and keeps you from feeling pain. Potential side effects of sedation, although there are fewer than with general anesthesia, include headache, nausea, and drowsiness.

These side effects usually go away quickly. Local anesthesia. This is the type of anesthesia least likely to cause side effects, and any side effects that do occur are usually minor. You may be sore or experience itching where the medication was injected.

You may be given a different type of anesthetic or a medication to counteract the side effects. Regional anesthesia. Regional anesthesia is a type of pain management for surgery that numbs a large part of the body, such as from the waist down. This type of anesthesia, including spinal blocks and epidurals, is often used for childbirth. In fact, an epidural is the most common type of pain control used for labor and delivery. These act mainly at nucleus tractus solitarius and areas of reticular formation blocking NK-1 receptors.

They are more effective in inhibiting emesis than nausea. Dose is 40 mg PO 1—2 h prior to surgery. It is an NK-1 receptor antagonist with a h half-life. Aprepitant was significantly more effective than ondansetron for preventing vomiting at 24 h and 48 h after surgery and in reducing nausea severity in the first 48 after surgery. Dose is 50— mg PO plus ondansetron 4 mg, not yet approved for use. Dose is 70— mg PO and has not been approved for use.

It blocks the synthesis of prostaglandins, which sensitizes nerves to other commonly involved neurotransmitters in emesis control. It also may have central effect by antagonizing 5-HT 3 receptors or corticosteroid receptors in the nucleus tractus solitarius. Its side effects are gastrointestinal upset, insomnia. Preoperative dexamethasone 8 mg enhances the postdischarge quality of recovery in addition to reducing nausea, pain, and fatigue. A recent study reported that intraoperative dexamethasone 4—8 mg may confer an increased risk of postoperative infection.

It is a relatively selective D 2 receptor antagonist, administered toward the end of the surgery. It prevents PONV at doses between 2.

Propofol has antiemetic properties even with subhypnotic dose range. These possess a direct antiemetic effect along with opioid-sparing effect. In a meta-analysis, perioperative systemic alphaadrenoceptor agonists clonidine and dexmedetomidine showed a significant albeit weak and short-lived antinausea effect.

It is a specific serotonergic and noradrenergic antidepressant. Midazolam 2 mg when administered 30 min before the end of the surgery was as effective against PONV as ondansetron 4 mg. There is no difference between crystalloids and colloids when similar volumes were used in surgeries associated with minimal fluid shifts. P 6 -stimulation with 10 different acupuncture modalities reduces nausea and vomiting. Neuromuscular stimulation over median nerve reduces the incidence of PONV in early postoperative period.

Strategies not effective for PONV prevention are music therapy, isopropyl alcohol inhalation, intraoperative gastric decompression, the proton pump inhibitor esomeprazole , ginger root, nicotine patch to nonsmokers, and cannabinoids nabilone and tetrahydrocannabinol. Combination therapy for PONV prophylaxis is preferable to using a single drug alone.

Pharmacologic combination therapy that can be used are as follows:[ 7 ]. The 5-HT 3 antagonists have better antiemetic than antinausea efficacy but are associated with headache. These drugs can be used in combination with droperidol which has greater antinausea efficacy and is associated with lower risk of headache. Multimodal approach combines nonpharmacologic and pharmacologic prophylaxis along with interventions that reduce baseline risk.

A planned multimodal approach starting from preoperative period can significantly reduce the incidence of PONV. Depending on the level of risk, prophylaxis should be initiated with monotherapy or combination therapy using interventions that reduce baseline risk, nonpharmacologic approach, and antiemetics. No prophylaxis is recommended for patients at low risk for PONV except if they are at risk of medical consequences from vomiting, for example, patients with wired jaw.

Antiemetic prophylaxis, although cannot eliminate the risk for PONV, can significantly reduce incidence. When developing management strategy for each individual patient with moderate and high risk, the choice should be based on patient preference, cost efficiency, level of PONV risk, patient's pre-existing condition avoid QT-prolonging drugs in patients with QT-syndrome and TDS in closed angle glaucoma patients. When rescue therapy is required, the antiemetics should be chosen from a different therapeutic class than the drugs used for prophylaxis, or if no prophylaxis was given, the recommended treatment is low-dose 5-HT 3 antagonist.

The dose of 5-HT 3 antagonist used for treatment is smaller than those used for prophylaxis ondansetron 1 mg, granisetron 0. An emetic episode more than 6 h postoperatively can be treated with any of the drugs used for prophylaxis except dexamethasone, TDS, aprepitant, and palonosetron.

PONV prophylaxis should be considered for patients with moderate to high risk based on scoring system. Based on the level of risk, the patient can be treated with monotherapy or combination therapy of antiemetics along with nonpharmacologic approach and interventions for reducing baseline risk.

A planned multimodal approach starting from preoperative period most likely ensures success in the management of PONV, which significantly improves the quality of patient care and is cost-effective.

Abstract Postoperative nausea and vomiting PONV is one of the complex and significant problems in anesthesia practice, with growing trend toward ambulatory and day care surgeries.

Keywords: Nausea-vomiting, postoperative nausea and vomiting, postoperative nausea and vomiting prophylaxis, and rescue. Vomiting It is the forceful expulsion of even a small amount of upper gastrointestinal contents through the mouth.

Open in a separate window. Figure 1. Intraoperative factors Surgical factors: Type of surgery: Cholecystectomy and gynecological and laparoscopic surgeries are associated with high incidence of PONV[ 7 ] Duration of surgery: Longer duration surgeries are associated with increased incidence of PONV.

Nonsteroidal anti-inflammatory agents can be used in perioperative period to reduce opioid requirement Supplemental oxygen is no longer recommended for PONV prevention. Table 1 Classification of antiemetic drugs based on receptor antagonism.

Ondansetron Recommended dose is 4 mg IV at the end of surgery. Dolasetron Dose is Granisetron Dose 3 mg IV in combination with dexamethasone 8 mg IV is more effective than either drug alone. Tropisetron Dose is 2 mg IV at the end of surgery. Ramosetron Dose 0.

Palonosetron It is the second generation 5-HT 3 receptor antagonist with a longer half-life of 40 h. Side effects are visual disturbances, dry mouth, and dizziness. Histamine receptor antagonists These drugs block acetylcholine receptors in the vestibular apparatus and histamine receptors in the nucleus tractus solitarius. Promethazine Dose is Neurokinin-1 receptor antagonists It is a new group of drugs used for PONV treatment thought to prevent both acute and delayed emesis.

Aprepitant Dose is 40 mg PO 1—2 h prior to surgery. Cospitant Dose is 50— mg PO plus ondansetron 4 mg, not yet approved for use. Rolapitant Dose is 70— mg PO and has not been approved for use. In addition, the use of some over the counter substances such as Tantum or Strepsils can help alleviate acute sore throat pain.

Complaints of sore throat after tracheal intubation: a prospective evaluation. Eur J Anaesthesiol ; Teeth damage How common is it?

Teeth damage is a rare but very unfortunate complication of general anesthesia, roughly occurring in cases. The most frequently injured teeth are the upper front ones the upper incisors 25; Can it be prevented?

Although the anesthetists are always very careful, prevention of dental damage is not always possible. Several devices have been used such as mouth-guards and bite-blocks but provide no guarantee. Moreover, these devices may make it more difficult to place to place the breathing tube. Dental injury associated with anesthesia: a report of , anesthetics given over 14 years.
