Mean platelet volume, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and early post-operative anesthesia complications

Abstract Objectives We aimed to establish the relationship between pre-operatively measured mean platelet volume (MPV), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) values and early anesthetic complications like bronchospasm & laryngospasm and hypotension in patients undergoing adenotonsillar surgery and non-adenotonsillar surgeries in both pediatric and adult population. Methods Patients from both sexes aged 1–63 years, and the American Society of Anesthesiology (ASA) physical status I–II were included in the study with elective adenotonsillectomy and non-adenotonsillar surgeries. Results In total, we included 330 patients in our study. The respiratory complications observed significantly more frequent in pediatric adenotonsillar surgery group (p=0.001). When the post-operative complications were compared with the MPV, NLR and PLR values, it was observed that the MPV values were significantly higher in patients who had hypotension (p=0.01) and PLR values were significantly higher in pediatric adenotonsillectomy group who developed bronchospasm and laryngospasm. There was no relationship between other complications and the laboratory values of the groups. Conclusions In the study, we found that PLR values were significantly high in the pediatric patients having hypoxia who underwent adenotonsillectomy. MPV values were significantly high in the patients who had hypotension in the early post-operative period. Based on these findings, it has been suggested that pre-operative PLR value can be a predicting guide for bronchospasm, laryngospasm. On the other hand, MPV values can be used as a guide in terms of predicting hypotension.
