    Anesthetic Management in Pediatric Orthotopic Liver Transplant For Fulminant Hepatic Failure and End-stage Liver Disease
    (2014) Camkiran, Aynur; Araz, Coskun; Balli, Sevgi Seyhan; Torgay, Adnan; Moray, Gokhan; Pirat, Arash; Arslan, Gulnaz; Haberal, Mehmet; https://orcid.org/0000-0003-1470-7501; https://orcid.org/0000-0002-4927-6660; https://orcid.org/0000-0002-6829-3300; https://orcid.org/0000-0003-2498-7287; https://orcid.org/0000-0002-3462-7632; 24635805; AAJ-4576-2021; AAJ-5221-2021; AAE-1041-2021; AAJ-8097-2021
    Objectives: We assessed the anesthetic management and short-term morbidity and mortality in pediatrics patients who underwent an orthotopic liver transplant for fulminant hepatic failure or end-stage liver disease in a university hospital. Material and Methods: We retrospectively analyzed the records of children who underwent orthotopic liver transplant from May 2002 to May 2012. Patients were categorized into 2 groups: group fulminant hepatic failure (n=22) and group end-stage liver disease (n=19). Perioperative data related to anesthetic management and intra-operative events were collected along with information related to postoperative course and survival to hospital discharge. Results: Mean age and weight for groups fulminant hepatic failure and end-stage liver disease were 8.6 +/- 2.7 years and 10.8 +/- 3.8 years (P= .04) and 29.2 +/- 11.9 kg and 33.7 +/- 16.9 kg (P= .46). There were no differences between the groups regarding length of anhepatic phase (65 +/- 21 min vs 73 +/- 18 min, P= .13) and operation time (9.1 +/- 1.6 h vs 9.5 +/- 1.8 h, P= .23). When compared with the patients in group fulminant hepatic failure, those in group end-stage liver disease more commonly had a Glasgow Coma score of 7 or less (32% vs 6%, P= .04). Compared with patients in group fulminant hepatic failure, those in group end-stage liver disease were more frequently extubated in the operating room (31.8% versus 89.5% P <.001). Postoperative duration of mechanical ventilation (2.78 +/- 4.02 d vs 2.85 +/- 10.21 d, P = .05), and the mortality rates at 1 year after orthotopic liver transplant (7.3% vs 0%, P = .09) were similar between the groups. Conclusions: During pediatric orthotopic liver transplant, those children with fulminant hepatic failure require more intraoperative fluids and more frequent perioperative mechanical ventilation than those with end-stage liver disease.

    Anesthetic and Perioperative Management of Nontransplant Surgery in Patients After Liver Transplant
    (2017) Ersoy, Zeynep; Ayhan, Asude; Ozdemirkan, Aycan; Polat, Gulsah Gulsi; Zeyneloglu, Pinar; Arslan, Gulnaz; Haberal, Mehmet; 0000-0003-0767-1088; 0000-0003-2312-9942; 0000-0002-3462-7632; 0000-0003-3299-6706; 0000-0001-8285-0372; 28260430; AAF-3066-2021; AAH-7003-2019; C-3736-2018; AAJ-8097-2021; AAJ-2066-2021
    Objectives: We aimed to document the anesthetic management and metabolic, hemodynamic, and clinical outcomes of liver-graft recipients who subsequently undergo nontransplant surgical procedures. Materials and Methods: We retrospectively analyzed the data of 96 liver-graft recipients who underwent 144 nontransplant surgeries between October 1998 and April 2016 at Baskent University Hospital. Results: The median patient age at the time of nontransplant surgery was 32 years, and 35% were female (n = 33). The median time between transplant and nontransplant surgery was 1231 days. The most frequent types of nontransplant surgery were abdominal (22%), orthopedic (16%), and urologic (13%). Seventy patients had an American Society of Anesthesiologists status of 2 (49%); the status was 3 in 71 patients (49%) and 4 in 3 patients (2%). Of the 144 procedures, 23 were emergent (16%) and 48% were abdominal. General anesthesia was used in 69%, regional anesthesia in 19%, and sedoanalgesia in 11%. Twenty-five patients required intraoperative blood-product transfusion (17%). Intraoperative hemodynamic instability developed in 17% of patients, and hypoxemia developed in 2%. Eleven patients remained intubated at the end of surgery (8%). Of the 144 procedures, 19 (13%) required transfer to the intensive care unit, 108 (75%) transferred to the ward, and the remaining 17 (12%) were discharged on the same day. Eight patients developed respiratory failure (6%), 7 had renal dysfunction (5%), 4 had coagulation abnormalities (3%), and 10 had infectious complications (7%) in the early postoperative period. The median hospital stay was 4 days, and 5 patients (4%) developed rejection during hospitalization. Five patients died of respiratory or infectious complications (4%). Conclusions: Most liver-graft recipients who undergo nontransplant surgery are given general anesthesia, transferred to the ward after the procedure, and discharged without major complications. We suggest that orthotopic liver transplant recipients may undergo nontransplant surgery without any post operative graft dysfunction.
