Anesthesiology and pain medicine

Pain control in children is still a therapeutic dilemma. Preschool patients are affected from undesirable effects of postoperative pain more than adults. Tonsillectomy is associated with a high incidence of postoperative pain, not only complicating the recovery, but also delaying patients discharge. ⋯ The study demonstrated that the both subcutaneous and intravenous injections of ketamine, at the end of the operation, were safe and effective for post-tonsillectomy pain control. Ketamine reduced postoperative analgesic medications consumption without increasing the risk of complications.

Effective control of postoperative pain remains one of the most important and pressing issues in the field of surgery and has a significant impact on our health care system. In too many patients, pain is treated inadequately, causing them needless suffering and they can develop complications as an indirect consequence of pain. Analgesic modalities, if properly applied, can prevent or at least minimize this needless suffering and these complications. ⋯ The results of our study indicate that for patients who are scheduled for hip surgery, both continuous paravertebral and continuous epidural analgesia are effective in controlling postoperative pain but that the former has several crucial advantages.

Post-operative nausea and vomiting (PONV) is one of the common problems after laparoscopic cholecystectomy. ⋯ Intravenous injection of 8 mg Dexamethasone or 3 mg Granisetron before anesthesia induction had similar effects in prophylaxis of nausea and vomiting after laparoscopic cholecystectomy.

Blood loss in spine surgery is an important issue, even though it has been understudied compared with hip and knee arthroplasty. ⋯ As an oral premedication, clonidine can reduce surgical blood loss in lumbar spine posterior fusion surgery, even at the same levels of mean arterial pressure (MAP) with the control group. Its use can be studied in more complicated spine surgeries, such as scoliosis and spinal deformity surgeries.
