Breast Hypertrophy, Pain, Postoperative
Conditions
Brief summary
In breast reduction surgery, pain control is usually performed with tumescent anesthesia, thoracic epidural anesthesia, intercostal nerve blocks and paravertebral block applications. Tumescent anesthesia is also preferred by plastic surgeons because of the varying risk of thoracic epidural anesthesia and paravertebral block applications. After the Erector spinae block was first described by Forero in 2016, it was reported to have been applied in many cases, including breast surgery. It is considered to be a safer block because of the presence of paravertebral block-like activity and the location where the needle is guided away from the pleura. The investigators aimed to compare postoperative analgesia consumption, pain scores and patient satisfaction of erector spine block with tumescent anesthesia in patients who underwent reduction mammoplasty operation under general anesthesia in this double-blind prospective randomized study.
Detailed description
Patients aged 18-65 years undergoing bilateral reduction mammoplasty. Patients were randomly divided into two groups with closed envelope to perform tumescent anesthesia and erector spinae block. All patients were premedicated with oral midazolam 0.5 mg/ kg preoperatively. All patients received standard general anesthesia protocol as induction with 2-3 mg/kg iv propofol and 1-1.5 mcg/kg fentanyl and 0.6 mg/kg iv rocuronium. Endotracheal intubations were performed 7.0 or 7.5 endotracheal tubes with the patient in a supine position. Anesthesia maintenance was with sevoflurane 0.5/kg/mg remifentanil infusion and in a 50% O2 -50% air mixture. Standard monitoring of the patients included of heart rate, invasive systolic, diastolic and mean blood pressure and peripheral oxygen saturation and the operating times were recorded. At approximately 30 minutes before the end of surgery, 8mg dexketoprofen IV was administered to all patients. At the end of the operation, all the patients were performed with iv PCA(Patient Controlled Analgesia). Demographic data such as age, weight, and height of the patients were recorded. After patients informed about pain score NRS (Numeric Pain Rating Scale) and patient satisfaction score ( one to ten) recorded by the nurse of PACU and ward.
