Objective: To compare sensitivity, specificity, receiver operating characteristic (ROC), and area under the curve (AUC) values using the modified Frailty Index 11 (mFI-11), EuroSCORE II, and combined mFI-11 and EuroSCORE II to predict in-hospital mortality and composite morbidities.

Design: Retrospective cohort study SETTING: Songklanagarind Hospital, a tertiary care center in southern Thailand.

Participants: Elderly patients age ≥60 years who underwent elective open-heart surgical procedures on a pump between January 2017 and December 2022 were included.

We aimed to evaluate the potential anxiolytic effects of premedication with pregabalin, compared with diazepam and placebo. We conducted this non-inferiority, double-blind, randomized controlled trial in ASA classification I-II patients aged 18-70 years, scheduled for elective surgery under general anesthesia. They were allocated to receive pregabalin (75 mg the night before surgery and 150 mg 2 h before surgery), diazepam (5 and 10 mg in the same manner) or placebo.

Objective: We examined the consequences of perioperative respiratory event (PRE) in terms of hospitalization and hospital cost in children who underwent ambulatory surgery.

Methods: This subgroup analysis of a prospective cohort study (ClinicalTrials.gov: NCT02036021) was conducted in children aged between 1 month and 14 years who underwent ambulatory surgery between November 2012 and December 2013.

Background: We aimed to construct a prediction tool for postoperative oxygen therapy and determine predictors of duration of use among children undergoing non-cardiac surgery.

Methods: Data from this case-control study was obtained from a database of 9820 children aged < 15 years who underwent general anesthesia between January 2010 and December 2013 at a tertiary care hospital in southern Thailand. The primary outcomes were the use and duration (hours) of postoperative oxygen therapy (cases).

Purpose: To determine whether perioperative desaturation (PD) in preschool children undergoing non-cardiac surgery is associated with subsequent impairment of intelligence or subsequent change in age-specific weight and height percentile.

Method: A historical-concurrent follow-up study was conducted in children aged ≤ 60 months who underwent general anesthesia (GA) for non-cardiac surgery between January 2008 and December 2011 at Songklanagarind Hospital. Children who developed PD (PD group) and children who did not develop perioperative respiratory events (no-PRE group) were matched on sex, age, year of having index GA, type of surgery and choice of anesthesia.

Background: Knowledge of the excess hospital costs and prolonged length of stay attributable to perioperative respiratory event (PRE) in pediatric anesthesia is useful for hospital planning. In this study, we compared costs (excess hospital costs and indirect costs) and length of hospital stay between children who had PRE and did not have PRE for noncardiac surgery at a tertiary care hospital in southern Thailand.

Methods: A prospective matched cohort study was conducted in children aged <15 years who underwent general anesthesia between November 2012 and December 2013 at Songklanagarind Hospital.

Background: Postoperative sore throat (POST) is a frequent consequence following ETT intubation, which may negatively affect the postoperative course and patient satisfaction. Benzydamine hydrochloride is a topically-applied non-steroidal anti-inflammatory drug (NSAID). The authors evaluated the analgesic effect of benzydamine hydrochloride dripping on the ETT cuff on POST.

Background: Although there has been growing evidence from off-label use of recombinant activated factor VII (rFVIIa) in surgical bleeding, there is limited information on prediction scores.

Methods: A retrospective study was conducted from 2004 to 2009. The primary outcome was efficacy of bleeding control.

Background And Objectives: As part of the Thai Anesthesia Incidents Study of anesthetic adverse outcomes, we evaluated the incidence and factors related to cardiac arrest during spinal anesthesia.

Methods: During a 12-mo period (March 1, 2003, to February 28, 2004), a prospective, multicenter registry of patients receiving anesthesia was initiated in 20 hospitals (7 university, 5 tertiary, 4 general, and 4 district hospitals) across Thailand. Anesthesia personnel reported patient-, surgery-, and anesthetic-related variables and adverse outcomes, including cardiac arrest during spinal anesthesia (defined as the time period from induction of spinal anesthesia until the end of operation).

Objective: The Thai Anesthesia Incidents Monitoring Study (Thai AIMS) was aimed to identify and analyze anesthesia incidents in order to find out the frequency distribution, clinical courses, management of incidents, and investigation of model appropriate for possible corrective strategies.

Material And Method: Fifty-one hospitals (comprising of university, military, regional, general, and district hospitals across Thailand) participated in the present study. Each hospital was invited to report, on an anonymous and voluntary basis, any unintended anesthesia incident during six months (January to June 2007).

Objective: Determine the appropriate model for incident study of adverse or undesirable events in more extensive levels from primary to tertiary hospitals across Thailand.

Material And Method: The present study was mainly a qualitative research design. Participating anesthesia providers are asked to report, on anonymous and voluntary basis, by completing the standardized incident report form as soon as they find a predetermined adverse or undesirable event during anesthesia, and until 24 hours after the operation.

Background: The present study was part of the Thai Anesthesia Incidents Study (THAI Study) of anesthetic adverse outcomes.

Objective: To determine factors related to intraoperative oxygen desaturation (SpO2 < or =85% or < 90% for more than 3 min).

Material And Method: During a 12-month period (February 1, 2003 - January 31, 2004), a prospective multicentered registry of patients receiving anesthesia was conducted in 20 hospitals across Thailand Anesthesia personnel filled up patient-related, surgical-related, and anesthesia related variables and adverse outcomes including intraoperative oxygen desaturation.

Aneurysms of the extracranial internal carotid artery (ICA) are uncommon. These lesions usually present with symptoms of transient ischemic attacks (TIA) from emboli and cranial nerve dysfunction from compression. The primary objective of treatment is to prevent a permanent neurologic deficit arising as a result of atheroembolism.
