Background: Percutaneous nephrolithotomy (PNL) poses a risk of hypothermia. Additionally, general anesthesia lowers the thresholds for shivering and vasoconstriction, which leads to dysfunction of central thermoregulation. Perioperative hypothermia is associated with adverse outcomes after surgery. In this study, we aimed to demonstrate that prewarming for 10 min can effectively prevent early hypothermia during PNL. Methods: A total of 68 patients scheduled for elective PNL were recruited to this study from January to June 2022, but two patients were excluded because of a change in the surgical plan...

Postoperative visual loss (POVL) is an infrequent yet consequential complication that can follow cardiac surgical interventions. This systematic review aims to provide a comprehensive analysis of the incidence of POVL after cardiac surgery and to delineate the associated risk factors. A comprehensive search was conducted in major medical databases for relevant studies published up to September 2022. Eligible studies reporting on the incidence of POVL and identifying risk factors in patients undergoing cardiac surgery were included...

BACKGROUND: Hypothermia on admission is associated with increased mortality in preterm infants. Drugs administered to pregnant women is implicated in its occurrence. Since magnesium sulfate has a myorelaxant effect, we aimed evaluating the association of hypermagnesemia at birth and admission hypothermia (axillary temperature <36.5°C) in preterm infants. METHODS: We performed a secondary analysis of a prospective cohort study database including inborn infants <34 weeks, without congenital malformations...

Currently, there is no specific perioperative nursing standard for RARC based on the ERAS concept. This retrospective study investigates to analyze the effect of RARC-ERAS nursing program on VTE and other clinical outcomes in patients undergoing RARC surgery. This retrospective study included 216 patients undergoing RARC surgery From January 1, 2022 to December 30, 2023, and propensity score adjustment analysis was applied. The study compares a control group receiving traditional nursing and an observation group receiving RARC-ERAS nursing program...

Excision of necrotic and devitalized tissues of deep burns is key for optimal care of burn injuries. However, the modality of early tangential excision followed by skin grafting proposed by Zora Janzekovic five decades ago was not received initially with great enthusiasm. At present, it developed to become the standard of care (SOC) despite the special expertise it necessitates and the general anesthesia it requires in addition to several drawbacks including excessive blood loss, risk of hypothermia, and most important potential excision of normal non-burned tissues...

BACKGROUND: This study aimed to investigate the impact of intraoperative hypothermia on the recovery period of anesthesia in elderly patients undergoing abdominal surgery. METHODS: A prospective observational study was conducted based on inclusion and exclusion criteria. A total of 384 elderly patients undergoing abdominal surgery under general anesthesia were enrolled in a grade A tertiary hospital in Chengdu, Sichuan Province from October 2021 and October 2022...

Cardiac arrest after acute pulmonary edema in pregnancy is an uncommon event but one with a potentially disastrous outcome. We report the case of a pregnant woman with preeclampsia who presented with rapidly advancing pulmonary edema and subsequently went into cardiac arrest on arrival at the operating room. A perimortem cesarean section was performed in addition to cardiopulmonary resuscitation and anesthesia. These simultaneous treatments resulted in excellent maternal and neonatal outcomes. Moreover, therapeutic brain hypothermia was performed...

OBJECTIVES: The aim of this study was to compare the analgesic efficacy and the effect on physiological variables and behavior of the use of tramadol, methadone and morphine as preoperative analgesia in healthy cats undergoing elective ovariohysterectomy. METHODS: Cats undergoing ovariohysterectomy were randomly assigned to receive one of the following premedication treatments intramuscularly: methadone (0.2 mg/kg; n = 10); morphine (0.2 mg/kg; n = 10); or tramadol (3 mg/kg; n = 10)...

OBJECTIVE: As the population of patients aged 65 years and older increases, the number of older adult patients undergoing surgery also increases. Older adults are vulnerable to hypothermia due to age-related changes in the thermoregulatory center, which leads to reduced subcutaneous fat tissue, vasomotor response, and heat production. Thus, they are more likely to suffer complications, including cardiovascular changes, blood coagulation disorders, infections, and delayed recovery from surgery...

PURPOSE: 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. PATIENTS AND METHODS: 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)...

PURPOSE: To evaluate the perioperative health care professionals' knowledge of evidence-based inadvertent perioperative hypothermia management. DESIGN: A descriptive, cross-sectional study. METHODS: The research sample consisted of 219 perioperative nurses and anesthesia technicians working in the university hospital and participating in perioperative care. Data were collected by the researchers using a questionnaire that included descriptive characteristics of health care professionals and inadvertent perioperative hypothermia management between March and April 2021...

BACKGROUND Intraoperative and postoperative hypothermia of patients can be caused by the use of anesthetic drugs and the complicated and time-consuming procedures of interventional surgery. This retrospective study included 184 patients to investigate the incidence and factors associated with hypothermia during intraoperative anesthesia in a single center in China between January and October 2023. MATERIAL AND METHODS A convenient sampling method was used to select 184 patients who underwent general anesthesia intervention in a tertiary hospital in Sichuan Province from January to October 2023 as the study population...

PURPOSE: Though the finger is generally recommended for pulse oxygen saturation (SpO2 ) monitoring site, its reliability may be compromised in conditions of poor peripheral perfusion. Therefore, we compared the performance of nasal septum SpO2 monitoring with finger SpO2 monitoring relative to simultaneous arterial oxygen saturation (SaO2 ) monitoring in generally anesthetized patients. METHODS: In 23 adult patients, comparisons of SpO2 measured at the nasal septum and finger with simultaneous SaO2 were made at four time points during the 90 min study period...

BACKGROUND: With the popularity of liposuction surgery, more awareness should be obtained regarding complications. Liposuction has been thought of as a safe procedure with a very low incidence of major complications. However, life-threatening risks of liposuction have rarely been reported. METHODS: We present a case of a 36-year-old woman who developed cardiac arrest during a liposuction procedure, and we present a literature review. RESULTS: She was previously healthy and had no risk factors for pulmonary embolism...

OBJECTIVES: Hypothermia is highly common in patients undergoing gynecological surgeries under general anesthesia, so the length of hospitalization and even the risk of mortality are substantially increased. Our aim was to develop a simple and practical model to preoperatively identify gynecological surgery patients at risk of intraoperative hypothermia. METHODS: In this retrospective study, we collected data from 802 patients who underwent gynecological surgery at three medical centers from June 2022 to August 2023...
