Nitrous Oxide, or laughing gas, is used as an analgesic, and as an anesthetic for pre-operative procedures. Nitrous oxide is delivered to the hospital in standard tanks and is supplied through the medical gas system at around 345 kPa, or 50 psi. Mixture gases (N2O and O2) can be used in colonoscopy.
Colonoscopy is the gold standard investigation for large bowel disease. With the increase in demand, pressure is on clinics to shorten lengths of time per procedure in addition to maintaining high levels of patient safety. Analgesia has always been the mainstay of adequate pain relief, but it leads to prolonged recovery and lengths of hospital stay, in addition to increased risk of cardio‐respiratory side effects. N2O/O2 mixtures have been used for its effective analgesic effect and short half life and provides an alternative method of sedation for colonoscopy procedures.
Objectives: The primary objective was to compare the overall effectiveness of nitrous oxide mixtures to other types of pain relief used during colonoscopy procedures to provide adequate pain/discomfort relief.
The secondary objective was to compare between nitrous oxide and other types of pain relief with respect to hospitalisation/recovery time, side effects, patients and endoscopists satisfaction, and colonoscopy completion rates.
We can provide N2O gases for you.
