“Preventing peri-operative maternal and neonatal hypothermia after skin-to skin contact: a pilot RCT study” Mrs Aliona Vilinsky-Redmond BSc, RM, MSc, RMT Staff midwife-PhD student
Background -current practice and problem- SSC started in OT in 2011 Feasible, but regular incidents of hypothermia 1 literature review, 3 audits and 1 pilot RCT¹ to review the problem Pilot RCT published PhD started Ongoing Systematic Review² and full size RCT 1 Newborn babies are predisposed to Hypothermia therefore increasing risks of hypoglycaemia and associated complications Maternal analgesic requirements and risk of sepsis and haemorrhage increase with post operative hypothermia 2 Facilitate Skin to skin contact¹ immediately after delivery Neonatal Temperature check after skin to skin in theatre and in PACU Maternal temperature check x 2 in PACU Babies transferred skin to skin in mothers arms Nappy, blankets Hat
Objectives Review the feasibility of a future RCT Determine the sample size of the study population active peri-operative warming Vs current practice-> prevents neonatal hypothermia during/after SSC up to 2 h post-delivery? He’s the father not the anesthetist
Methods and Sample Methods: Randomised°, single-blinded¹, interventional² study Ethical approval: Rotunda REC (approved December 2014) Sample size: (20 mothers/babies) 10 intervention group (IV fluids warmed to 39°C) 10 usual care group (IV fluids at room temperature 25°C approx.) Data collection: prospective observational data (T measurements)¹ captured on hardcopy audit tool (collected between January-February 2015) Data analysis: MS Excel, SPSS version 22 (Mann-Whitney test) Excluded criteria: Babies born vaginally Babies born outside theatre hours (08:00-16:00) or at weekends High risk babies ie. Preterm deliveries, congenital anomalies, multiple births Babies born by Emergency LSCS Women under GA ¹Standards: babies dressed with hat and nappy Wrapped 2blankets and a towel Warm under ohio prior removing from OT Check 4 anxilliary temps with the same digital thermometer (say where) Document room temps from each case (both OT and PACU) Babies dressed before T/f to wards
Results Temperature checks Warm fluids group hypothermia Usual care group P value* Pre-anaesthesia 0/10♀ P= .673 During CS 1/10♀ (35.9°C) 3/10♀ (mean 35.8°C) P= .016 In PACU 4/10♀ (BH given) P= .005 On admission to PSNT 2/10♀ (35.8°C & 35.9°C) P= .989 SSC time 81.3 minutes 82 minutes P= .983 Mean OT temperature 24.04°C 25.22°C P= .045 No statistical significant differences between new-born T in both groups (p= .057) Clinically significant as 3/10 babies (control group) became mildly hypothermic (36.1°C and 36.2°C) Vs 1/10 baby (intervention) (36.4°C)
Conclusions Limitations: Use of pre-warmed IV fluids reduced the incidence of maternal peri-operative hypothermia in comparison with the standard care group Still uncertain as to whether it had any significant effect on the prevention of neonatal hypothermia Limitations: Study was single-blinded Room T in OT/PACU were difficult to maintain at a standard temperature due to air-conditioning dysfunctions at the time of the data collection Room T difference between the two groups, could potentially be a major bias in this study
