There are few side effects, other than vomiting, with short-term use. [1] [2] With long-term use anemia or numbness may occur. [2] It should always be given with at least 21% oxygen. [2] It is not recommended in people with a bowel obstruction or pneumothorax. [2] Use in the early part of pregnancy is not recommended. [1]
For pain relief after surgery, use can decrease the amount of inhalational anesthetic needed for emergence from anesthesia. [32] Balancing this medication and titrating the drug based on expected stimuli and the person's responses can result in stable blood pressure and heart rate throughout a procedure and a faster emergence from anesthesia ...
There is a risk in many types of pain management for the patient to take treatment that is less effective than needed or which causes other difficulties and side effects. [6] Some treatments for pain can be harmful if overused. [6]
Onset of pain relief is rapid and of a short duration. [4] Use is only recommended with direct medical supervision. [5] Common side effects include anxiety, headache, sleepiness, cough, and nausea. [5] Serious side effects may include kidney problems, liver problems, low blood pressure, and malignant hyperthermia.

Postanesthetic shivering is one of the leading causes of discomfort in patients recovering from general anesthesia. It usually results due to the anesthetic inhibiting the body's thermoregulatory capability, although cutaneous vasodilation (triggered by post-operative pain) may also be a causative factor.
Each drug has a benefit-risk profile and balancing the risk of no treatment with the competing potential risks of various therapies should be considered. [49] For people over the age of 65 years old, the balance between the benefits of pain-relief medications such as NSAIDS and the potential for adverse effects has not been well determined. [50]
However, surgery remained a treatment of last resort. Largely because of the associated pain , many patients chose certain death over surgery. Although there has been debate as to who deserves the most credit for the discovery of general anaesthesia, scientific discoveries in the late 18th and early 19th centuries were critical to the eventual ...
