Preventing Nausea After Surgery

Asking Your Anesthesiologist for Help Can Prevent Nausea, Speed Recovery


Updated June 02, 2014

After my breast biopsy and again after my lumpectomy, I woke up with an overwhelming sensation of nausea. When I talked about this with my coworkers, they said, "Everybody gets post-op nausea. Its just part of surgery." That didn't sound right -– so before my mastectomy, I grilled my general surgeon about it. The good news is that you can request pretreatment with anti-nausea (antiemetic) drugs.

Anesthesia and Nausea After Surgery
Anesthesia drugs may be used to put you to sleep, or prevent pain during your surgery. That's a welcome benefit of anesthesia. However, those same drugs may cause you to feel nauseous and to retch or vomit.

Who Gets Sick After Surgery?
It's true that not everybody gets sick after surgery. If you're an adult and have these risk factors, you may have a greater chance of having postoperative nausea and vomiting:

  • Female
  • Nonsmoker
  • History of motion sickness
  • Previous episode of postoperative nausea and vomiting
  • Surgery that takes more than 30 minutes
  • General anesthesia using nitrous oxide
  • Opium-based drugs given for pain
Risks of Nausea and Vomiting After Surgery
If you have a bad reaction to anesthesia, you might vomit enough fluids to cause dehydration, resulting in low levels of electrolytes and minerals circulating in your system. Retching and repeated vomiting can leave your tummy muscles feeling sore and weak. In rare cases, you can develop a rip in the lining of the tissue at the end of your esophagus where it meets your stomach –- in which case you might see some blood when you vomit. There are good treatments for all of these problems. But you must speak up and ask for help, if you need it.

Prevention of Nausea After Surgery
Your anesthesiologist can help you prevent nausea caused by anesthesia drugs. You can be given special medications just before surgery that will prevent or greatly reduce your nausea and vomiting. Be sure to take these medications exactly as prescribed because otherwise they might not work at all. Your anesthesiologist can also give you anti-nausea drugs in your intravenous line during surgery. In the recovery room, you can be given pills or a Scopolamine patch behind your ear to help prevent post-surgical nausea and vomiting. Many of these nausea medications will make you drowsy, so just take it easy.

Drug-Free Nausea Prevention
If you want to try a drug-free alternative, perhaps you could try an acupressure wristband. A 2004 study of data from 4,858 surgeries showed that when patients had wrist acupuncture or acupressure, "the use of P6 acupoint stimulation can reduce the risk of nausea and vomiting after surgery, with minimal side effects." These patients either wore an acupressure wristband or had needle acupuncture, laser stimulation, or manually applied acupressure. Researchers said that patients had few side effects from the acupressure, and that these methods compared favorably with antiemetic drugs. Pressure on your P6 wrist acupressure point signals your brain to release serotonin, dopamine or endorphins, which block other chemicals that are causing the nausea and vomiting.

Ask Your Anesthesiologist For Help
You will meet with your anesthesiologist at your pre-operative appointment or just before surgery. It is to your great benefit to be honest and accurate when talking to an anesthesiologist about your health. Let them know if you'd had trouble with anesthesia in the past. Talk about any pain, nausea, or vomiting that you've had related to surgery. Ask what treatments can be given to help you. If you're nervous about surgery, you can even ask for a sedative. During your surgery, your anesthesiologist will be responsible for keeping you comfortable and watching your vital signs. Your anesthesiologist can be a great ally in your fight against breast cancer, so work with him to make your journey safer and easier.
