Sleep studies are often recommended before surgery to prevent unnecessary procedures and reduce the risk of complications. For example, a sleep study can determine whether a child needs a tonsillectomy. Sleep studies can also diagnose obstructive sleep apnea (OSA), which is associated with an increased risk of surgical complications. Patients with OSA who are diagnosed and treated before surgery are less likely to develop serious cardiovascular complications.

What You'll Learn
Sleep studies can prevent unnecessary surgery
Sleep studies can also reduce the risk of complications following surgery. For example, patients with obstructive sleep apnea (OSA) who are diagnosed and treated before surgery are less likely to develop serious cardiovascular complications such as cardiac arrest or shock. Sleep studies are therefore mandated before gastric bypass surgery, as there is a strong association between OSA and obesity.
Sleep studies can also determine the effectiveness of surgery. For example, a tonsillectomy does not always cure sleep apnea, so a pre-operative sleep study can establish a baseline for comparison. If the apnea is much better following surgery, then further treatment such as CPAP (continuous positive airway pressure) can be avoided.

Sleep studies can reduce the risk of serious cardiovascular complications following surgery
Sleep apnea can lead to serious health problems if it goes undetected. Those who are overweight or have high blood pressure are predisposed to developing sleep apnea. Symptoms of sleep apnea may include heavy snoring, pauses in breathing during sleep, and excessive sleepiness during the day. Sleep apnea can cause the brain to wake the person up hundreds of times per night to resume breathing, leading to broken and ineffective sleep.
Sleep studies can help determine the presence of sleep apnea before surgery. If sleep apnea is present, the tonsils should be removed. Sleep studies can also help determine the effectiveness of surgery in treating sleep apnea. For example, if a child undergoes a tonsillectomy without a pre-operative sleep study and is later found to have sleep apnea, it will be difficult to determine how much the apnea has improved.
Sleep studies are particularly important for patients undergoing gastric bypass surgery, as the prevalence of OSA is high in this group. Pre-operative screening of these patients can be done by cardiopulmonary polygraphy or even more simplified systems.

Sleep studies can also help to reduce the risk of complications following surgery. Patients with obstructive sleep apnea (OSA) who are diagnosed and treated for the condition prior to surgery are less likely to develop serious cardiovascular complications such as cardiac arrest or shock. Sleep studies are therefore mandated before gastric bypass surgery, as the prevalence of OSA is particularly high in these patients.

Sleep studies can diagnose sleep apnea
Sleep apnea can lead to serious health problems if it is not detected. Those who are overweight or have high blood pressure are predisposed to developing sleep apnea. Symptoms of sleep apnea may include heavy snoring, pauses in breathing during sleep, and excessive sleepiness during the day. Sleep apnea can also cause cardiovascular complications such as cardiac arrest or shock.
Sleep studies are therefore mandated for patients undergoing gastric bypass surgery, as the prevalence of sleep apnea is particularly high in this group. Sleep studies can also help prevent unnecessary surgery. For example, just because a child snores doesn't mean that they need their tonsils out, even if the tonsils are large. A sleep study will tell us if sleep apnea is present. If so, the tonsils should be removed.
Sleep studies can also help determine the effectiveness of surgery. For example, tonsillectomy doesn't always cure sleep apnea, even if the tonsils were large. Therefore, if a child undergoes tonsillectomy without a pre-operative sleep study, and they are found to have sleep apnea, it will never be known how improved the apnea was.

Sleep studies can be used to screen for obstructive sleep apnea (OSA)
Sleep studies are therefore mandated and pre-operative polysomnography could be performed, as it is the most cost-effective strategy for diagnosing OSA. Pre-operative screening by cardiopulmonary polygraphy or even more simplified systems is a feasible alternative that is currently routinely applied.

Frequently asked questions
Sleep studies are recommended before surgery to prevent unnecessary surgery, reduce the risk of complications following surgery, and determine the effectiveness of surgery.
A sleep study is a test that monitors your sleep patterns and breathing. It can help diagnose conditions such as sleep apnea, which is associated with an increased risk of surgical complications.
If you are diagnosed with sleep apnea before surgery, you can receive treatment to reduce the risk of serious cardiovascular complications such as cardiac arrest or shock.
