EP620 - Incidence of Perioperative hypothermia in elective surgeries at a district hospital in NHS - loop completion

Abstract Aim To investigate the incidence of peri-operative hypothermia (core temperature ≤ 36 ⁰C) in all elective surgical patients at a district hospital in NHS and compare the results to the previous study. To understand the contributing factors to hypothermia in the elective surgical patients. Methods Inadvertent perioperative hypothermia (IPH) is defined as a core body temperature <36.0°C. It is a common consequence of anaesthesia, which increases morbidity and potentially increases mortality. National Institute of Health and Care Excellence (NICE) Guideline 65 which summarises best practice for the prevention and treatment of hypothermia in adults undergoing surgery. Prospective analysis of 100 electively listed surgical patients at NMGH. We prospectively studied all the electively listed general surgery, breast, gynaecology, urology, orthopaedics patients from 1 July 2023 to 1 September 2023. Exclusion criteria – All emergency cases. Pre-operative temperature, pre-induction temperature, intra-operative, post-procedure, temperature in recovery and temperature post recovery were recorded. Temperature measurement was via tympanic or temporal thermometers. All statistical calculations were performed on the StatsDirect3 software. Results Preoperative 36.55, Pre-induction 36.55, Intra-operative 36.5, Postoperative is 36.5, Recovery 36.5 Post recovery is 36.6, Theatre temperature 19.5 Conclusion Statistically significant correlation was observed between the intraoperative temperature and the pre-induction temperature as well as the theatre ambient temperature (p < 0.0001). A theatre temperature of 18 °C has a predicted intraoperative temperature of 34.4 °C and a temperature of 19 °C has a predicted temperature of 36.3 °C. Median pre-induction temperature at NMGH is 36.5 °C and the predicted intraop temp is 36 °C. If the pre-induction temperature raises to 37.2 °C the predicted intraop temperature is 36.6 °C.

Effect of Aggressive Warming versus Routine Thermal Management on the Incidence of Perioperative Hypothermia in Patients Undergoing Thyroid Surgery: A Prospective, Randomized, Double-Blind Controlled Trial.

Despite the implementation of various insulation measures, the incidence of hypothermia during thyroid surgery remains high. This randomized controlled study aimed to evaluate the effects of aggressive thermal management combined with resistive heating mattresses to prevent perioperative hypothermia in patients undergoing thyroid surgery. 142 consecutive patients scheduled for elective thyroid surgery were enrolled in the study. They were randomly and equally allocated to the aggressive warming or routine care groups (n = 71). The patients' body temperature was monitored before the induction of anesthesia until they returned to the ward. The primary outcome was the incidence of perioperative hypothermia. Secondary outcomes included postoperative complications, such as mortality, cardiovascular complications, wound infection, shivering, postoperative nausea and vomiting (PONV), visual analog scale (VAS) pain scores, fever, headache and hospital length of stay (LOS). In our study, the results showed that a significantly higher rate of hypothermia was observed in the routine care group compared with the aggressive warming group. The incidence of perioperative hypothermia was 19.72% (14/71) in the aggressive warming group and 35.21% (25/71) in the routine care group (P < 0.05). The incidence of shivering in the aggressive warming group (1.41%) was significantly lower than that in the routine care group (11.27%) (P < 0.05), and a one-day reduction in hospital length of stay was observed in the aggressive warming group (P < 0.05). There was no significant difference in mortality or other postoperative complications, such as cardiovascular complications, wound infection, PONV, pain, fever or headache, between the two groups (P > 0.05). Our results suggest that aggressive thermal management combined with resistive heating mattresses provided improved perioperative body temperature and reduced the incidence of perioperative hypothermia and shivering compared to routine thermal management.

Effect of timing of intraoperative administration of paracetamol on postoperative shivering: A randomised double-blind controlled trial.

Paracetamol (PCM) has an anti-shivering effect and may also exacerbate intraoperative hypothermia. This study compares the incidence of shivering as the primary outcome and the incidence of perioperative hypothermia (<36°C) and the time to the analgesic requirement as secondary outcomes when PCM was administered after induction of anaesthesia or towards the end of surgery. In this randomised study, 225 adult patients of either gender undergoing elective surgical procedures under general anaesthesia with an expected duration of surgery of 1-4 h were studied. They received intravenous (IV) PCM 15 mg/kg (maximum 1 g) immediately after anaesthesia induction (Early PCM group), 30 min before completion of surgery (Late PCM group) or no PCM (Control group). IV morphine 0.1 mg/kg was administered for analgesia in all three groups. The Chi-square test and repeated measures analysis of variance followed by Tukey's test were used for statistical analysis. The incidence of shivering was lower in Late PCM (12%) than in Early PCM (29.3%) (P = 0.009) and Control groups (30.6%) (P = 0.005). The incidence of postoperative hypothermia was also significantly lower in the Late PCM group than in the Early PCM (P = 0.002) and Control groups (P = 0.016). Early PCM and Control groups did not significantly differ. The number of patients requiring postoperative analgesia was smaller, and the time to the analgesic requirement was longer in Late PCM compared to other groups. Administration of IV PCM 30 min before completion of surgery results in a lower incidence of postoperative shivering and hypothermia when compared to PCM administered after induction of anaesthesia or no PCM.

Incidence of perioperative hypothermia in a high-quality high-volume spay/neuter setting and association with environmental temperature

Introduction: Perioperative inadvertent hypothermia (PIH) can prolong anesthetic recovery times. Study goals included determining PIH incidence (rectal temperature&lt;36°C (96.8°F)) in the high-quality high-volume spay/neuter (HQHVSN) setting and evaluating associations between environmental temperature and PIH incidence. Secondary objectives included evaluating associations between PIH incidence, anesthesia recovery times, and postoperative pain. Methods: Prospective observational cohort study conducted at five HQHVSN shelters enrolling dogs undergoing ovariohysterectomy or castration and cats undergoing ovariohysterectomy. Blankets and electric heating pads were only used routinely in the immediate postoperative period. Regression models were used to evaluate associations between PIH incidence, environmental temperature, and pain data. Results: One hundred and forty dogs undergoing 65 castrations and 75 ovariohysterectomies, and 161 cats were enrolled. Mean surgical times were 19.6 (8.0) min (canine ovariohysterectomies), 7.2 (3.0) min (canine castrations), and 10.6 (3.6) min (feline ovariohysterectomies). PIH incidence was 22% (95% CI = 17–27). The risk of developing PIH was associated with environmental temperature, with a 22% increase in the odds of experiencing PIH for each degree centigrade decrease in environmental temperature (OR = 1.22, 95% CI = 1.03–1.44, P = 0.02) over a recorded range of 15.6–26.1°C (60.1–79.0°F). In cats, PIH was associated with a prolongation of time to extubation by 3.8 min (95% CI 2.27–5.37, P = 0.01). On average, each degree centigrade reduction in rectal temperature at extubation was associated with an increase in pain scale of 0.51 units (95% CI = 0.06–0.97, P = 0.03) for both species. In dogs, each degree centigrade reduction in rectal temperature at extubation was associated with a reduction in mechanical threshold (indicating increased sensitivity to pain) of 1.40 N (95% CI = 0.44–2.35, P = 0.004). Conclusion: PIH is common in a spay/neuter population despite rapid surgical times and is associated with prolonged anesthetic recovery in cats and increased postoperative pain in cats and dogs. Raising the environmental temperature in operative and recovery areas may reduce incidence.

Self-warming blankets versus active warming by forced-air devices for preventing hypothermia: A systematic review and meta-analysis.

Unintended perioperative hypothermia is a significant complication for patients undergoing anesthesia. Different measures are routinely undertaken to prevent hypothermia and its consequences. The evidence comparing the impact of self-warming blankets and forced-air warming is scarce. Therefore, this meta-analysis aimed to evaluate the efficacy of self-warming blankets compared to forced-air devices regarding the incidence of perioperative hypothermia. We searched the Web of Science, Cochrane Central Register of Controlled Trials, PubMed, and Scopus for relevant studies from inception until December 2022. We included comparative studies with patients allocated to undergo warming using a self-warming blanket or forced air warming. All concerned outcomes were pooled as odds ratios or mean differences (MDs) in the meta-analysis models using Review Manager (RevMan version 5.4). Our results from 8 studies (597 patients) favored self-warming blankets over forced-air devices in terms of core temperature at 120 and 180 minutes after induction of general anesthesia (MD = 0.33, 95% confidence interval [CI] [0.14-0.51], P = .0006), (MD = 0.62, 95% CI [0.09-1.14], P = .02), respectively. However, the overall effect did not favor either of the 2 groups for the incidence of hypothermia (odds ratio = 0.69, 95% CI [0.18-2.62]). Ultimately, self-warming blankets have a more significant effect than forced-air warming systems in terms of maintaining normothermia of core temperature after induction anesthesia. However, the present evidence is not enough to verify the efficacy of the 2 warming techniques in the incidence of hypothermia. Further studies with large sample sizes are recommended.

The Effect of Sevoflurane Low-Flow Anesthesia on Preserving Patient Core Temperature

Introduction: Low-flow anesthesia (LFA) reduces the fresh gas flow (FGF) entering the anesthesia circuit and saves on the volatile agent used. In this study, the effect of LFA with sevoflurane on core temperature and the incidence of perioperative hypothermia were investigated. Methods: According to the FGF applied, patients were classified into three groups: LFA (1 L/min), medium-flow anesthesia (MFA = 2 L/min), and high-flow anesthesia (HFA = 4 L/min). Patients’ demographic data and the initial (T1) and final (T2) core temperatures during the operation were compared. Results: A total of 160 patients were included in the study. The T2 value of the HFA group was significantly lower than the LFA group (p = 0.028). Different flow values were found to have a significant effect on temperature change (F = 21.630, p < 0.001, partial eta squared = 0.216). There was a significant difference between the mean temperatures measured at two different times (F = 301.064, p < 0.001, partial eta squared = 0.657). The overall incidence of hypothermia was 32.5%, with 52 patients. Hypothermia (T²<36°C) incidences were not different between the LFA group and the MFA and HFA groups (p = 0.682). However, perioperative core temperature loss was significantly lower in the LFA group (p = 0.001). Conclusions: LFA using sevoflurane was not sufficient alone to significantly reduce the incidence of hypothermia. However, we have demonstrated that it may also have a beneficial effect on reducing perioperative temperature loss.

The incidence of inadvertent perioperative hypothermia in patients undergoing general anesthesia and an examination of risk factors.

Unintended perioperative hypothermia, defined as core body temperature less than 36°C, is closely related to many complications such as cardiovascular diseases, peroperative hemorrhagic diathesis and impairment of drug metabolism. Determination of the incidence of perioperative hypothermia and examination of risk factors may help to prevent hypothermia and its complications. We conducted a prospective, observational study of 2015 patients who underwent various operations under general anesthesia, and the risk factors of developing hypothermia were analysed. The incidence of perioperative hypothermia was 78.6%. The incidence of hypothermia within 2hours was 56.6%, and after 2hours, it was 100%. Mean age was 49.36±16.10, and 17.8% were over 65years old. The mean body mass index (BMI) was 27.96±3.94kg/m2 ; 60.8% of the patients had American Society of Anesthesiologists (ASA) I score, 33.4% had ASA II and 5.8% had ASA III; 35.8% of the patients had co-morbidities. Intravenous and irrigation fluids were unwarmed; 99.9% of the patients were warmed passively, and only 0.1% of patients received active heating intraoperatively. The incidence of hypothermia was higher in overweight (BMI≥25kg/m2 ), elderly (>65years) patients and those with co-morbidities. High American Society of Anesthesiologists (ASA) scores, grade 3-4 surgery, endoscopic surgery, duration of anesthesia>2hours, infusion or irrigation>1000mL significantly increased the incidence of hypothermia. The incidence of perioperative hypothermia found was high. Important risk factors were found as prolonged duration of anesthesia and surgery, advanced age, overweight, high ASA scores, major surgeries, endoscopic operations and unwarmed fluid administration. High incidence may be reduced by raising awareness, considering fossible risk factors and following the recommendations of the guidelines on prevention of perioperative hypothermia.

Incidence of Perioperative Hypothermia in Geriatric Patients Undergoing Elective Surgery

Changes in normothermia during surgery.

The aim of the study was to monitor changes in normothermia in patients undergoing surgery under general anaesthesia. Prospective, observational survey, where standardized, intentional observations, medical record statements and semi-structured interviews with patients and healthcare professionals were used for data collection. The group consisted of 95 patients, 18 years and older, undergoing surgery lasting 30 minutes and longer under general anaesthesia. The collection of data took place from October 2018 to March 2019 in operating theatres of the otorhinolaryngological department (40 patients), central operating theatres (55 patients), and in recovery rooms and intensive care units. Perioperative hypothermia (body temperature below 36°C) was demonstrated in 11 (11.6%) patients. Atemperature lower than comfortable body temperature (36.0-36.5°C) occurred in 47, i.e. almost half of the patients (49.5%), and no relationship was demonstrated between hypothermia and the value of the Body Mass Index. The duration of surgery and its effect on the decrease in body temperature was confirmed in patients operated on in the otorhinolaryngology theatres. Arelationship was confirmed between hypothermia and the length of the surgery (correlation coefficient -0.452; p=0.003). The incidence of perioperative hypothermia was demonstrated in 11.6% patients. No relationship was demonstrated between BMI and the development of hypothermia in our patients. Arecord sheet proposal for monitoring perioperative body temperature was published.

The effect of interscalene brachial plexus block with propofol sedation on preventing perioperative hypothermia during arthroscopic shoulder surgery.

BackgroundInterscalene brachial plexus block (ISBPB) is commonly used with general anesthesia for postoperative pain management in shoulder surgery. This study investigated the incidence of hypothermia and changes in the body temperature in patients undergoing arthroscopic shoulder surgery under ISBPB with propofol sedation.MethodsThis retrospective study enrolled 220 patients who underwent arthroscopic shoulder surgery. Patients were divided into general anesthesia (n = 34) and ISBPB with propofol sedation (n = 186) groups, and medical records were retrospectively compared. In addition, patients from the ISBPB group were further divided according to age (elderly [≥ 65 years], n = 98 vs. young [< 65 years], n = 88), and the incidence of hypothermia and changes in the body temperature were compared.ResultsTwenty-seven patients (12.3%) experienced perioperative hypothermia (range: 35.3–35.9℃). The incidence of perioperative hypothermia was 29.4% and 9.1% in the general anesthesia and ISBPB groups, respectively, and there was a significant difference between the two groups (P = 0.002). The incidence of perioperative hypothermia according to age in the ISBPB group was 9.2% and 9.1% in the elderly and young groups, respectively, and there was no significant difference between the two groups (P = 0.983).ConclusionsThe incidence of perioperative hypothermia during arthroscopic shoulder surgery under ISBPB with propofol sedation is lower than that under general anesthesia. Furthermore, when using ISBPB with propofol sedation, the incidence of perioperative hypothermia in elderly patients is similar to that in younger patients.

Effects of warming carbon dioxide pneumoperitoneum on the prognosis of patients undergoing pancreaticoduodenectomy by Da Vinci robot

Objective To study the effect of heated carbon dioxide pneumoperitoneum on the prognosis of patients undergoing pancreaticoduodenectomy by Da Vinci robot. Methods A total of 307 patients who underwent pancreaticoduodenectomy by Da Vinci robot from January 2016 to December 2018 were selected as subjects. 140 patients who underwent pancreaticoduodenectomy from January 2016 to April 2017 were selected as the control group, and room temperature carbon dioxide pneumoperitoneum was used. From May 2017 to December 2018, 167 patients were set as the intervention group, and heated carbon dioxide pneumoperitoneum was used. Body temperature, heart rate and blood oxygen saturation of the two groups were compared after entering the operating room, before anesthesia, before the establishment of carbon dioxide pneumoperitoneum and after the closure of carbon dioxide pneumoperitoneum, and the duration of operation, intraoperative blood loss, postoperative anesthesia recovery time, hospitalization time and postoperative complication rate were recorded. Results There was no significant difference in body temperature after entering the operating room, before the establishment of carbon dioxide pneumoperitoneum between the two groups (P>0.05). After the closure of carbon dioxide pneumoperitoneum, the decline range of the body temperature of the control group was(1.24±2.36) ℃, which was significantly higher than that of the intervention group (0.60±0.25) ℃, and the difference was statistically significant (t value was 6.892, P 0.05). The intraoperative blood loss, resuscitation time, drainage time was (291.08±265.42) ml, (27.04±10.89) min, (8.69±6.64) d in the intervention group and (364.29±309.28) ml, (32.60±12.17) min, (10.76±6.25) d in the control group, and the difference was statistically significant (t value was 2.232, 7.294, 2.789, P<0.05 or 0.01). There was statistically significant difference in The incidence of pancreatic fistula and biliary fistula, and length of hospital stay was 20 cases, 7 cases, (27.62±17.30) d in the intervention group, and 31 cases, 15 cases, (32.38±12.22) d in the control group, and the difference was statistically significant (χ2 value was 4.653, 4.870, t value was 6.284, P<0.05). Conclusions Warming carbon dioxide pneumoperitoneum can reduce the incidence of perioperative hypothermia and improve the prognosis of patients undergoing pancreaticoduodenectomy by Da Vinci robot.

Effects of combined warmed preoperative forced-air and warmed perioperative intravenous fluids on maternal temperature during cesarean section: a prospective, randomized, controlled clinical trial

BackgroundPreventing the frequent perioperative hypothermia incidents that occur during elective caesarean deliveries would be beneficial. This trial aimed at evaluating the effect of preoperative forced-air warming alongside perioperative intravenous fluid warming in women undergoing cesarean sections under spinal anesthesia.MethodsWe randomly allocated 135 women undergoing elective cesarean deliveries to either the intervention group (preoperative forced-air and intravenous fluid warming, n = 69) or the control group (no active warming, n = 66). The primary outcome measure was the core temperature change between groups from baseline to the end of the surgical procedure. Secondary outcomes included thermal comfort scores, the incidences of shivering and hypothermia (< 36 °C), the core temperature on arrival at the post-anesthesia care unit, neonatal axillary temperature at birth, and Apgar scores.ResultsTwo-way repeated measures ANOVA revealed significantly different core temperature changes (from the pre-spinal temperature to that at the end of the procedure) between groups (F = 13.022, P < 0.001). The thermal comfort scores were also higher in the intervention group than in the control group (F = 9.847, P = 0.002). The overall incidence of perioperative hypothermia was significantly lower in the intervention group than in the control group (20.6% vs. 51.6%, P < 0.0001).ConclusionsWarming preoperative forced-air and perioperative intravenous fluids may prevent maternal hypothermia, reduce maternal shivering, and improve maternal thermal comfort for patients undergoing cesarean sections under spinal anesthesia.Trial registrationThe study was registered with the Chinese Clinical Trial Registry (registration number: ChiCTR1800019117) on October26, 2018.

Perioperative hypothermia in colorectal surgeries: are we doing enough to prevent it?

To determine the incidence of hypothermia in patients undergoing colorectal surgery, and to identify factors that increase vulnerability to perioperative hypothermia. The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised medical records from May 2012 to June 2017 related to all patients aged >16 years of either gender who underwent colorectal procedures. Analysis about predictors of perioperative hypothermia was done using Stata 12. Of the 100 patients, 69(69%) were males. The overall mean age was 50.2±16.7 years. Majority cases had elective presentation 72(72%). Incidence of perioperative hypothermia was noted in 74(74%) patients. Postoperative morbidity was 16(16%), while mortality was 4(4%). Elective presentation and hypothermia before surgery were significantly associated with occurrence of intraoperative hypothermia (odds ratio: 4.5 and 1.3 respectively). Perioperative incidence of hypothermia was found to be quite high despite appropriate measures. Factors responsible need to be explored and rectified.

A comparison of postoperative outcomes with PDA ligation in the OR versus the NICU: a retrospective cohort study on the risks of transport

BackgroundAlthough patent ductus arteriosus (PDA) ligations in the Neonatal Intensive Care Unit (NICU) have been an accepted practice, many are still performed in the Operating Room (OR). Whether avoiding transport leads to improved perioperative outcomes is unclear. Here we aimed to determine whether PDA ligations in the NICU corresponded to higher risk of surgical site infection or mortality and if transport was associated with worsened perioperative outcomes.MethodsWe performed a retrospective cohort study of NICU patients, ≤37 weeks post-menstrual age, undergoing surgical PDA ligation in the NICU or OR. We excluded any infants undergoing device PDA closure. We measured the incidence of perioperative hypothermia, cardiac arrest, decreases in SpO2, hemodynamic instability and postoperative surgical site infection, sepsis and mortality.ResultsData was collected on 189 infants (100 OR, 89 NICU). After controlling for number of preoperative comorbidities, weight at time of procedure, procedure location and hospital in the mixed-effect model, no significant difference in mortality or sepsis was found (odds ratio 0.31, 95%CI 0.07, 1.30; p = 0.107, and odds ratio 0.40; 95%CI 0.14, 1.09; p = 0.072, respectively). There was an increased incidence of hemodynamic instability on transport postoperatively in the OR group (12.4% vs 2%, odds ratio 6.93; 95% CI 1.48, 35.52; p = 0.014).ConclusionPDA ligations in the NICU were not associated with higher incidences of surgical site infection or mortality. There was an increased incidence of hemodynamic instability in the OR group on transport back to the NICU. Larger multicenter studies following long-term outcomes are needed to evaluate the safety of performing all PDA ligations in the NICU.KeywordsPatent ductus arteriosus, Newborn infant, Neonatal intensive care unit, Surgical wound infection, Postoperative period, Hemodynamics

Perioperative inadvertent hypothermia among urology patients who underwent transurethral resection with either TURis or transurethral resection of the prostate method.

The purpose of the study was to investigate the incidence of perioperative hypothermia in urology patients undergoing transurethral resection with either TURis or transurethral resection of the prostate method and to recognize the risk factors that were responsible for the occurrence of hypothermia intraoperatively in these patients. It was a randomized prospective study. A total of 168 patients, according to American Society of Anesthesiologists physical status I-III, were scheduled for transurethral resection either with TURis or transurethral resection of the prostate method. We measured the core body temperature before (preoperative), during (perioperative) and after (postoperative) the surgery. Age, body mass index, American Society of Anesthesiologists score, duration of surgery, preoperative prostatic volume, and vital signs were also recorded. The prevalence of inadvertent hypothermia was 64.1% for the TURis group and 60% for the transurethral resection of the prostate group. Hypothermic patients in TURis group were significantly older (87.7 ± 1.7 vs 68 ± 6.7 years, p < 0.05) and had lower body mass index (26.9 ± 3.6 vs 29.2 ± 2.7, p < 0.05), while hypothermic patients in the transurethral resection of the prostate group were significantly older (86 ± 1.1 vs 70 ± 7.4 years, p < 0.05) and had notably higher duration of surgery (140.6 ± 28.9 vs 120.3 ± 14.3 min, p < 0.05) than normothermic patients. Perioperative inadvertent hypothermia among urology patients who underwent transurethral resection with both TURis and transurethral resection of the prostate method is of high incidence. We recommend monitoring of the temperature of core body of all these patients, especially those with advanced age and lower body mass index.

Encuesta de actitudes sobre vigilancia de la temperatura y protección térmica perioperatoria en Colombia

IntroductionPerioperative hypothermia is a common condition associated with serious complications and perioperative mortality. The incidence of perioperative hypothermia is between 30 and 70%. ObjectiveTo determine the status of perioperative monitoring and thermal protection in clinics and hospitals of high complexity in Colombia and the establishment of minimum safety standards of the Colombian Society of Anesthesiology to this respect. MethodsA survey with voluntary answers was administered to leaders of anesthesiology departments and surgical services of high complexity institutions in Colombia. The questionnaire had 20 items with an adaptive structure and was sent by email to a randomized list. Only fully completed questionnaires were analyzed. Results135 surveys were analyzed. Measurement of temperature is reported always or almost always in 27% of cases, while 45% have at least one method of intraoperative thermal protection. Barriers for monitoring temperature and for thermal protection were explored. ConclusionsTemperature monitoring and perioperative thermal protection is insufficient in the sample studied. The reasons are: limited availability of devices for monitoring and protection and lack of interest towards the subject. There is no acceptance of minimum safety standards of the Colombian Society of Anesthesiology because of the limited availability of thermometers, poor monitoring of intraoperative temperature and misuse of heating strategies.

Perioperative Hypothermia and Predictors of Intra-Operative Hypothermia among Patients Operated at Gondar university Hospital from March to April 2015

Background: Humans maintain constant body temperature within a wide range of changes in external environment. Core body temperature is maintained within narrow range; Enzyme systems in the body have narrow temperature ranges in which they function optimally for caring out different activities in the body as metabolism, conduction of nervous function and skeletal muscle contraction. Perioperative hypothermia is one of the major problems during surgery that can affect operated patients. It has been shown by different researchers that Perioperative hypothermia will result in to various adverse events such as myocardial ischemia, coagulopathy, delayed awakening and wound infections. Objective: The objective of this study was to determine incidence of perioperative hypothermia and determinant factors among patients operated in Gondar university hospital from March to April, 2015. Methods: A prospective observational study was conducted to determine incidence of perioperative hypothermia and associated risk factors among patients that underwent surgery in Gondar university hospital. All consecutive patients from both elective and emergency surgery were included in this study. Result: A total of 312 patients were participated in this study. The incidence of Pre, Intra and post-operative hypothermia were 23.4%, 49.7% and 50.6% respectively. Use of general anesthesia (AOR=2.3), co-morbidity (AOR=2.1), low body temperature before the start of anesthesia (AOR=4.7) and elective procedures (AOR=2.1) were found to be independent predictors of intra-operative hypothermia. Conclusion and Recommendation: The incidence of perioperative hypothermia is high in Gondar University Hospital. Passive and active warming techniques should be implemented in the hospital.
