Wristband’s are Post Surgery Nausea Wristbands
The most common complaint from patients who have surgery is the nausea and vomiting that often follows the operation. In fact, in one survey, the majority of surgery patients reported they would rather suffer from moderate post-op pain than suffer from Post-Operative Nausea and Vomiting (PONV). – It can be that distressing!
Post-Operative Nausea and Vomiting occurs in about 30% of all surgery patients, and can be as high as 70% in “high-risk” patients. Researchers have identified six factors that will cumulatively increase your chances of nausea and vomiting after surgery –
Patient Risk Factors that increase the chances of PONV:
1) Being a woman – Compared to men, three times as many women patients experience nausea and vomiting after an operation. This difference is attributed to the different hormones in men and women.
2) Being a Non-Smoker – Statistics from a very large research study (Sinclair, et al 1999) showed that smoking decreased the likelihood of PONV by 34%.
3) Having a history of Motion Sickness or previous PONV – This will increase the risk of PONV by two or three times, and is reported to be one of the strongest predictors of whether of not a patient will get sick after the surgery.
Surgery Procedures that increase the chances of PONV:
1) Premedication or Post-Op pain medication using Opiates (such as morphine) – These drugs are often given before an operation to sedate the patient, relieve pain, and prepare her for anesthesia. They are also given after an operation to relieve pain. The risk of PONV greatly decreases if your doctor is able to substitute a non-opiate analgesic instead.
2) Type of Anesthesia – Sinclair et al (1999) studied 17,638 consecutive outpatient surgeries, and found that general anesthesia (inhaled through a mask) increased the chances of post-surgery nausea by 11 times (!) compared with other types of anesthesia, such as local anesthesia, intravenous anesthesia, or peripheral nerve blocks.
3) Duration of Surgery/Duration of Anesthesia – The same study found that the longer it takes to complete the surgery means a greater chance of the patient suffering nausea and vomiting afterwards. Statistically, a 30 minute increase in the duration of anesthesia increased the likelihood of PONV by 59%.
In addition to the pain, distress, and discomfort suffered by patients with post-operative nausea and vomiting, there is an added economic burden that increases health care costs. PONV is the most common cause of delayed discharge and unplanned hospitalizations. And there is also the additional personnel time needed to care for a patient that is still sick.
Doctors’ response to PONV is to prescribe anti-nausea (anti-emetic) medications, after assessing the risk factors above. More risk factors receive more and stronger drugs. – Unfortunately, most of these drugs are expensive, limited in their effectiveness, and have unpleasant side effects (such as drowsiness, blurred vision, urinary retention, anxiety, and involuntary muscle contractions).
So now, more and more hospitals are trying acupressure wristbands, instead of anti-nausea drugs, as an alternative that is inexpensive and has no side effects. This has resulted in the many clinical research studies that prove the effectiveness of the BioBands method for relieving nausea and vomiting.
