Aim: Hypothermia (HT) is a common and serious problem during anesthesia. As the ratio of skin surface area to body volume is higher in neonates than in adults, heat loss and ultimately HT are more common in the intraoperative period. This study aimed to determine the incidence and independent risk factors of HT in the neonatal period. Materials and Methods: This retrospective observational cohort study included 63 patients who underwent neonatal surgery within a one-year period. HT was defined as body temperature <36 °C and the patients were divided into two groups: Group I (body temperature <36 °C) and Group II (≥36 °C). Demographic data, ASA score, operative diagnosis, duration of surgery and anesthesia, amount of fluid, inotrope and vasopressor therapy, amount of bleeding, amount of blood transfusion, preoperative and postoperative temperatures, and the heating methods of the patients were recorded. Results: The median age of the patients was 5 days (0-28 days) and their mean weight was 2,792±782 grams. The esophageal method was used for temperature monitoring in 88.9% (56 patients) and the rectal method in 10.1% (7 patients). HT developed in 54% of the patients. Caps and socks were used to prevent HT in 96.8% of the patients, forced-air warming blankets in 95.2%, warming gel mattresses in 27%, and fluid and blood warming devices in 17.5%. In the logistic regression model, the operating room temperature was identified as the only independent risk factor associated with neonatal HT. Conclusion: Despite the use of active and passive warming methods, the incidence of HT in the neonatal period was found to be high. Cold operating rooms were found to be the only independent factor associated with neonatal HT. [ABSTRACT FROM AUTHOR]

The article focuses on the study conducted to evaluate the effectiveness of four dried blood spot testing protocols screening for congenital hypothyroidism (CH) of new born that are transferred to the neonatal intensive care unit. It mentions that population-based retrospective cohort study and logistic regression methods are used in the study. It concludes that primary testing programmes do not incorporate and serial screening may fail to identify approximately half of newborns with CH.

Objective To explore the maternal demographic factors associated with operative births (instrumental vaginal births or caesarean section), after adjustment for health, interpersonal, pregnancy, labour and infant covariates. Design Nationally representative cohort study. Setting Women giving birth in the UK, during the period 2000-2002. Sample A total of 18 239 mother-infant pairs. Methods Multinomial logistic regression models were estimated to explore the relationship between demographic characteristics and mode of birth, stratified by parity. Main outcome measures Self-reported mode of birth, defined as unassisted vaginal birth, instrumental vaginal birth, emergency caesarean section and planned caesarean section. Results For primiparous women, operative births rose steeply with increasing maternal age. Women from lower occupational status households were at an increased risk of planned caesarean section. Mode of birth differed significantly by ethnicity. For multiparous women, a younger age at first birth was protective of a later caesarean section or instrumental vaginal birth at the cohort birth. Women with qualifications normally taken at the age 18 years were at an increased risk of planned caesarean section compared with women with degree-level qualifications. Mode of birth differed significantly by ethnicity, and non- UK born women were at an increased risk of emergency caesarean section. Conclusions The sociodemographic characteristics of UK women independently predict mode of birth. Further research is needed to establish to what extent sociodemographic differences in mode of birth are a reflection of the attitudes and behaviours of women, or health professionals, and are therefore amenable to change.
