The aim of this study was to investigate the relationship between NLR, PLR and postoperative complications in children undergoing adenotonsillectomy and adenoidectomy.

Between the dates of February 1, 2018 and June 30, 2018, patients between 2-10 years of age, ASA I-II, elective adenotonsillectomy and adenoidectomy under general anesthesia were planned to be included in the study. The number of neutrophils, lymphocytes and platelets will be taken from the hospital registry system taken preoperatively and the NLR and PLR ratios will be calculated.

All patients in the operating room will be started with routine monitoring and anesthesia. Hemodynamic data during surgery will be recorded. The entrance to the operating room (T1), 5 minutes after the start of anesthesia (T5), 15 minutes (T15), 30 minutes (T30) and 45 minutes (T45) will be recorded in the follow-up form of the anesthesia. The fasting period of the patients and the drugs and fluids applied during surgery will be recorded from the anesthesia form. At the end of the operation, the patients who were taken to the recovery room at the end of the surgery will be evaluated with 1 point, 15 minutes, 30 minutes, 1 hour and 4 hours and 6 hours vomiting using the 4 point nausea scale.

Introduction to recovery room using Modified Eastern Ontario Children's Hospital Pain Scale (mCHEOPS), postoperative pain at 15 min, 30 min, 1 hr and 4 hr. Analgesic requirement will be recorded. Bronchospasm, agitation, etc. will be recorded by evaluating whether there are complications.
