Efektivitas Penggunaan Blanket Warmer untuk Pencegahan Hipotermi pada Pasien Post-Operative dengan Pengaruh Anastesi Spinal

Introduction

Efektivitas penggunaan blanket warmer untuk pencegahan hipotermi pada pasien post-operative dengan pengaruh anastesi spinal. Blanket warmer efektif cegah hipotermi pasca-operasi pada pasien anestesi spinal. Studi ini menunjukkan peningkatan suhu tubuh signifikan, direkomendasikan untuk kenyamanan & keamanan pasien.

Abstract

Background: Postoperative hypothermia is a common complication frequently occurring in patients undergoing spinal anesthesia. This condition can delay recovery, increase the risk of wound infection, and prolong the length of hospital stay. One method used to maintain the patient's body temperature is the use of a blanket warmer. Objective: To determine the effectiveness of blanket warmer usage in preventing hypothermia in postoperative patients undergoing spinal anesthesia. Methods: This study employed a case study design with a one-group pretest-posttest approach without a control group. The sample consisted of 12 postoperative patients in the Recovery Room of RSUD dr. Tjitrowardojo Purworejo. The patients underwent surgical procedures with spinal anesthesia. The intervention group received blanket warmer therapy for 10 minutes during the postoperative recovery phase. Body temperature was measured before and after the intervention using an axillary thermometer for one minute. Results: The use of a blanket warmer demonstrated a significant increase in patients' body temperature before and after the intervention (p= 0.001, p<0.05). The majority of patients in the intervention group successfully maintained a mean body temperature of 36.32°C. Conclusion: Blanket warmers are effective in preventing hypothermia in postoperative patients undergoing spinal anesthesia. The use of this device is recommended as part of the standard postoperative care to enhance patient comfort and safety.

Review

The submitted manuscript, "Efektivitas Penggunaan Blanket Warmer untuk Pencegahan Hipotermi pada Pasien Post-Operative dengan Pengaruh Anastesi Spinal," addresses a clinically important issue: the prevention of postoperative hypothermia, particularly in patients undergoing spinal anesthesia. Postoperative hypothermia is a well-recognized complication associated with adverse outcomes such as delayed recovery and increased infection risk. The study's objective to assess the effectiveness of blanket warmers in mitigating this risk is timely and relevant, aiming to improve patient care in the recovery room setting. The abstract reports a significant increase in body temperature following the intervention, suggesting a potential benefit of this simple and accessible therapy. While the study tackles an important topic, the methodological approach presents several limitations that temper the strength of its conclusions. The design, described as a "case study with a one-group pretest-posttest approach without a control group," inherently restricts the ability to definitively attribute observed changes solely to the blanket warmer intervention. Without a control group for comparison, it is challenging to rule out other confounding factors or the natural rewarming process that might occur post-anesthesia. Furthermore, the small sample size of 12 patients significantly limits the generalizability of the findings to a broader population, and the intervention duration of only 10 minutes may be too brief to provide robust evidence for sustained prevention effectiveness. Despite these methodological constraints, the study provides preliminary evidence supporting the utility of blanket warmers in elevating body temperature in immediate postoperative care for patients under spinal anesthesia. The finding that the majority of patients maintained a mean body temperature of 36.32°C post-intervention is encouraging for clinical practice. Given the known benefits of normothermia, the recommendation to incorporate blanket warmers into standard postoperative care, as suggested by the authors, holds practical value for enhancing patient comfort and safety. However, to establish a more definitive causal link and strengthen the evidence base, future research should consider a robust randomized controlled trial with a larger sample size, a dedicated control group, and potentially a longer observation period to assess the sustained effect of the intervention across diverse patient populations and clinical settings.
