The Effect of Different Intrathecal Doses of Meperidine on Postoperative Pain Relief in Patients Undergoing TURP Surgery

Transurethral resection of prostate (TURP) surgery has still continued to be the gold standard among the surgical treatments applied for benign prostatic hyperplasia (BPH), today [1]. TURP operations, it is more commonly preferred compared to general anaesthesia since it allows the early diagnosis of negativities such as regional anaesthesia fluid loading, bladder perforation, and TURP Sydrome. When the local anaesthetics are used appropriately and attentively in spinal anaesthesia, they have very few side effects. [2-4] Most of the patients who underwent a TUR-P operation are in their advanced ages and have respiratory and cardiac comorbidities. Therefore, it is important for such patients to prevent hypotension, bradycardia, and respiratory distress related to spinal anaesthesia [4]. (4) In order to achieve an efficient anaesthesia for the TUR-P operation, it is required to form the block at T10 level. Insufficient anaesthesia causes additional problems for the patient. Injection of low dose opioids together with local anaesthetics in regional blocks increases the potency of analgesia [5-7].
