RESUMEN
Perioperative fluid management remains a challenging aspect of paediatric liver transplantation (LT) because of the risk of postoperative complications and haemodynamic instability. Limited research has specifically investigated the impact of fluid management and transfusion on mortality and morbidity in pediatric LT patients. This systematic review summarizes the evidence regarding perioperative fluid management and its clinical outcomes in paediatric LT patients. All primary studies published in English evaluating perioperative fluid management in paediatric LT patients were eligible. PubMed, EBSCOHost, Embase, Proquest, and Google Scholar databases were searched from inception to December 19, 2023. Risks of bias were assessed using the Joanna-Briggs Institute checklist. The results were synthesized narratively. Five retrospective cohort studies of good-excellent quality were included in this review. Two studies evaluated intraoperative fluid administration, one study compared postoperative fluid balance (FB) with outcomes, and two studies compared massive versus non-massive transfusion. A higher mortality rate was associated with intravenous lactated ringer's (LR) than with normal saline, but not with massive transfusion (MT). Longer hospital stays were correlated with MT, >20% positive FB in the first 72 hours, and greater total intraoperative blood product administration. Higher intraoperative fluid administration was associated with a greater thrombotic risk. Additionally, intraoperative MT and lR infusion were associated with an increased risk of 30-day graft loss and graft dysfunction, respectively. Fluid management may impact the outcomes of paediatric LT recipients. These findings underscore the need for more studies to explore the best fluid management and evaluation strategies for children undergoing LT.
RESUMEN
BACKGROUND AND OBJECTIVES: The erector spinae plane block (ESPB) and classical thoracolumbar interfascial plane (TLIP) block can reduce postoperative pain in lumbar surgery. In this study, we compared the efficacy of ESPB and classical TLIP block in providing perioperative analgesia in patients undergoing lumbar posterior decompression and stabilization by comparing postoperative pain, opioid consumption, and IL-6 and IL-10 serum concentrations between ESPB and classical TLIP block. METHOD: This was a prospective, double-blinded, randomized controlled trial in tertiary referral hospitals. Forty patients were randomized into two equal groups, each receiving either ESPB or classical TLIP block. The primary outcome was the difference in IL-6 and IL-10 serum concentrations at baseline and 6 h after lumbar posterior decompression and stabilization. The secondary outcome was total opioid consumption and pain score 24 h post-operatively. RESULT: There were no significant differences between the ESPB and classical TLIP block groups in pain score, IL-6 and IL-10 concentration change, and total opioid consumption post-operatively. There was a significant difference in the time until the first dose of morphine was needed between the ESPB and classical TLIP block groups (300 min vs. 547.5 min; p = 0.002). CONCLUSION: ESPB and classical TLIP block performance during lumbar surgery have comparable pain scores, IL-6 and IL-10 concentration differences pre- and post-operation, and total opioid consumption post-operatively. However, classical TLIP block provides a prolonged duration of analgesia. TRIAL REGISTRATION: ClinicalTrials.gov NCT04951024.
