Background: Perioperative airway changes due to anesthesia and surgery could change a normal airway at induction to a risky airway at extubation.Objectives: The objective is to evaluate primarily the degree of airway changes, as quantified by the modified Mallampati (MMP) class, after spine surgery in the prone position. Secondary to assess the time required for these changes to revert back to the preoperative state and their correlation with other demographic and surgical variables.Methods: The present prospective observational study was conducted in a tertiary care hospital after ethical approval and trial registration. Fifty ASA I and II patients aged 18-65 years of both sex and undergoing spine surgery in prone positions were included. Supine MMP grade was observed preoperatively and at one, two, four, 24, and 48 hours postoperatively.Statistical analysis: IBM SPSS version 22 (IBM Corp, Armonk, NY) was used. Mean values were compared using paired t-tests and medians by the Wilcoxon test. The Spearman correlation was used to assess a relationship. The time for recovery was analyzed by Kaplan-Meir analysis.Results: An increase in MMP grade was observed at one hour postoperatively in 46 (92%) patients. Changes reverted back in 45 (98%) patients by 24 hours postoperatively. A weak positive correlation with age, weight, body mass index, duration of surgery, perioperative drop in hemoglobin, and a moderate positive correlation with fluid administered and estimated blood loss was recorded.Conclusions: An increase in postoperative MMP occurs in the majority of patients undergoing prone position spine surgery which may persist up to 48 hours. So, more vigilance and caution are warranted should reintubation be needed postoperatively.
Background: Hydroxyethyl starch solutions which have been introduced some three decades ago, have been extensively used for treatment of intraoperative hypovolaemia. Aims and Objectives: The present prospective study was conducted to study changes in post-operative renal function and coagulation profile in patients undergoing orthopedic hip surgery under spinal anesthesia after coloading with 6% HES 130/0.4. Materials and Methods: Seventy patients, aged between 50 and 80 years, of either sex, belonging to ASA physical Status I and II, scheduled for orthopedic hip surgery under spinal anesthesia were included in the study. As per the group allocation, coloading was done with 7.5 mlkg-1 of either Group RL or 6% 130/0.4 Group HES during the 1st h of surgery. Venous samples were withdrawn before the day of surgery, on the day of surgery, and on the 3rd day of surgery. Results: No statistically significant difference between renal and coagulation profile was found among groups. Conclusion: Thus, we recommend using tetrastarch (6% HES 130/0.4) for intraoperative hypovolemia in elderly patients with normal renal function and coagulation profile undergoing orthopedic hip surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
