The Portland intensive insulin therapy effectively controls acute hyperglycemic change after graft reperfusion during liver transplantation. However, the time-consuming sophistication acts as a barrier leading to misinterpretation and decreasing compliance to the protocol; thus, we newly introduced an application software “Insulin protocol calculator” which automatically calculates therapeutic bolus/continuous insulin doses based on the Portland protocol. Methods: Of 144 patients who underwent liver transplantation, 74 patients were treated before the introduction of “Insulin protocol calculator” by using a paper manual, and 70 patients were treated by using the application. Compliance was defined as the proportion of patients treated with exact bolus/continuous insulin dose according to the Portland protocol. Results: Compliance was significantly greater in app group than in paper group regarding bolus dose (94.5% and 86.9%, P < 0.001), continuous dose (88.9% and 77.3%, P = 0.001), and both doses (86.6% and 73.8%, P < 0.001). Blood glucose concentration was significantly lower in app group at 3 h (125 ± 17 mg/dl vs. 136 ± 19 mg/dl, P = 0.014) and 4 h (135 ± 22 mg/dl vs. 115 ± 15 mg/dl, P = 0.029) after graft reperfusion. Acute hyperglycemic change during 30 min was more prominent in app group while hyperglycemia incidence was 71.4% vs. 54.1% (P = 0.031). However, hyperglycemia risk was comparable at 2 h (31.4% vs. 31.1%, P = 0.964), and even insignificantly lower in app group at 3 h (7.1% vs. 19.5%, P = 0.184). Conclusions: Compliance to the Portland protocol was significantly improved after introducing the application software; post-reperfusion hyperglycemia was better controlled. “Insulin protocol calculator” is cost-effective and time-saving with potential clinical benefits

Purpose: To lessen the physical, cosmetic, and psychological burden of donors, purely laparoscopic donor hepatectomy (PLDH) has been proposed as an ideal method for living donors. Our study aimed to prospectively compare the effect of PLDH and 2 other types of open living donor hepatectomy (OLDH) on postoperative pain and recovery. Methods: Sixty donors scheduled to undergo donor hepatectomy between March 2015 and November 2017 were included.Donors were divided into 3 groups by surgical technique: OLDH with a subcostal incision (n = 20), group S; OLDH with an upper midline incision (n = 20), group M; and PLDH (n = 20), group L. The primary outcomes were postoperative pain and analgesic requirement during postoperative day (POD) 3. Other variables regarding postoperative recovery were also analyzed. Results: Although pain relief during POD 3, assessed by visual analog scale (VAS) score and analgesic requirement, was similar among the 3 groups, group L showed lower VAS scores and opioid requirements than group M. Moreover, group L was associated with a rapid postoperative recovery evidenced by the shorter hospital length of stay and more frequent return to normal activity on POD 30. Conclusion This pilot study failed to verify the hypothesis that PLDH reduces postoperative pain. PLDH did not reduce postoperative pain but showed faster recovery than OLDH.

Background: Fontan-associated liver disease (FALD) is a hepatic disorder caused by hemodynamic changes and systemic venous congestion following the Fontan procedure. FALD includes liver cirrhosis and hepatocellular carcinoma (HCC), both of which may require liver transplantation (LT). However, the Fontan circulation, characterized by elevated central venous pressure and reduced cardiac output, is a challenging issue for surgeons and anesthesiologists.Case: We report a living-donor LT for the treatment of HCC. The patient was a 24-year-old male who underwent the Fontan procedure for pulmonary atresia and right ventricle hypoplasia. We focused on maintaining enough blood volume for cardiac output without causing pulmonary edema, as the patient is not well adapted to changes in volume. Owing to a multidisciplinary approach, the surgery was successfully performed without fatal adverse events. Conclusions To our knowledge, this is the first case of isolated LT in a recipient who became an adult after having undergone the Fontan procedure.

PURPOSE: Whereas continuous renal replacement therapy (CRRT) has been utilized during liver transplantation (LT), there was a lack of evidence to support this practice. We investigated the adverse events at the perioperative periods in recipients of LT who received preoperative CRRT without intraoperative CRRT. METHODS: We retrospectively reviewed medical records of adult patients (age ≥ 18 years) who received LT between December 2009 and May 2015. Perioperative data were collected from the recipients, who received preoperative CRRT until immediately before LT, because of refractory renal dysfunction. RESULTS: Of 706 recipients, 42 recipients received preoperative CRRT. The mean (standard deviation) Model for end-stage liver disease score were 49.6 (13.4). Twenty-six point two percent (26.2%) of recipients experienced the serum potassium > 4.5 mEq/L before reperfusion and treated with regular insulin. Thirty-eight point one percent (38.1%) of recipients were managed with sodium bicarbonate because of acidosis (base excess <−10 mEq/L throughout LT). All patients finished their operations without medically uncontrolled complications such as severe hyperkalemia (serum potassium > 5.5 mEq/L), refractory acidosis, or critical arrhythmias. Mortality was 19% at 30 day and 33.3% at 1 year. CONCLUSION: Although intraoperative CRRT was not used in recipients with severe preoperative renal dysfunction, LT was safely performed. Our experience raises a question about the need for intraoperative CRRT.

PURPOSE: This study aimed to report intraoperative abortion of adult living donor liver transplantation (LDLT). METHODS: From June 1997 to December 2016, 1,179 adult LDLT cases were performed. 15 cases (1.3%) of intraoperative abortions in LDLT were described. RESULTS: Among 15 cases, 5 intraoperative abortions were donor-related, and remaining 10 cases were recipient-related. All donor-related abortions were due to unexpected steatohepatitis. Among remaining 10 recipient-related intraoperative abortions, unexpected extension of hepatocellular carcinoma was related in 5 cases. Two cases of intraoperative abortions were related to bowel inflammation, and 2 cases were associated with severe adhesion related to previous treatment. One recipient with severe pulmonary hypertension was also aborted. CONCLUSION: Complete prevention of aborted LDLT is still not feasible. In this regard, further efforts to minimize intraoperative abortion are required.

OBJECTIVE: As the demands of pharmacist's role and quality performance have increased, the verification of pharmacist's ability has been required. In this study, we aimed to select appropriate items for assessment of pharmacist's knowledge, attitude and performance. METHODS: Based on the pharmacist job analysis, we selected duties and tasks in consideration of applying pharmacy practical examination through brainstorming of internal researchers and group discussion with experts. Survey was conducted to evaluate the tasks according to the criteria detailed below: Realistic, Understandable, Measurable, Behavioral and Achievable (RUMBA). The subjects included professors at colleges of pharmacy and instructors of institutional or community pharmacy settings. RESULTS: Nine duties including 41 tasks were drawn for the survey through primary internal researchers. Of the 90 respondents, 95.6% were professors or preceptors who was engaged in practical training, and 62.2% had more than five years of practical experience. As a result of survey and discussion with expert panel, selected seven duties were selected as followings: ‘Patient (customer) reception’, ‘Drug preparation and distribution’, ‘Patient care’, ‘Administration’, ‘Patient counseling’, ‘Non-prescription medication counseling’, and ‘Provision of drug information’. The final 20 tasks from seven duties were chosen to assess skills that a pharmacist should be able to perform. CONCLUSION: This is the first study to select the items that can be included in pharmacist practical examination in the future, based on the RUMBA criteria. As a next step, it is necessary to study how to implement these items.

INTRODUCTIONWe studied the effect of head rotation on the relative position of the right common carotid artery (CCA) and the right internal jugular vein (IJV) in patients with laryngeal mask airway (LMA) insertion to evaluate the accuracy of anatomical landmarks for right IJV cannulation.

METHODSWe simulated needle insertion to the right IJV on sonograms via the central landmark approach and an approach using the external jugular vein, in patients with LMA insertion (n = 50) or endotracheal intubation (E-tube, n = 50). Overlap index and successful simulation rates were measured according to the different degrees of head rotation.

RESULTSThe overlap index between the right CCA and the right IJV increased with greater degrees of head rotation. It was significantly greater in the LMA insertion group than in the E-tube group in the following head rotation positions: neutral, 15° and 45°. The success rate of the simulation was lower in the LMA insertion group than in the E-tube group. In the LMA insertion group, the success rate of the simulation was highest (62%) with the central landmark approach and in the 15° head rotation position.

CONCLUSIONIn the LMA insertion group, the overlap index increased incrementally with greater head rotation degrees (from neutral to 45°). The central landmark approach and 15° head rotation position appear to be the optimal puncture site and degree of head rotation for right IJV cannulation in patients with LMA insertion.

INTRODUCTIONThere have been intermittent reports of peroneal neuropathy (PN) occurring after liver transplantation. Although PN may not be viewed as a serious complication by liver transplant (LT) recipients who require the transplant for survival, PN can significantly reduce quality of life. The incidence of PN appears to have increased after the use of gel pads was introduced. These gel pads, which are placed under patients' knees during surgery, are used to reduce lower back strain and prevent contact between the peroneal nerve at the fibular head and the hard surface of the operating table. The aim of the present study was to investigate the association, if any, between the use of gel pads and the incidence of PN.

METHODSThe medical records of 261 adult LT recipients were retrospectively reviewed. The recipients were divided into gel pad (n = 167) and non-gel pad (n = 94) groups. The incidence and possible risk factors of PN were compared between the two groups.

RESULTSThe overall incidence of PN was 8.0% (21/261). The occurrence of PN was significantly higher in the gel pad group than in the non-gel pad group (10.8% vs. 3.2%; p < 0.05). Other possible risk factors were comparable between the two patient groups.

CONCLUSIONAs the use of gel pads may increase the incidence of PN, we recommend against the use of gel pads under the knees of LT recipients.

BACKGROUND: High model for end-stage liver disease (MELD) scores (> or =35) is closely associated with poor posttransplantation outcomes in patients who undergo living donor liver transplantation (LDLT). There is little information regarding factors that negatively impact the survival of patients with high MELD scores. The aim of this study was to identify factors associated with 3-month mortality of patients after LDLT. METHODS: We retrospectively analyzed 774 patients who underwent adult LDLT with right lobe grafts between 1996 and 2012. Exclusion criteria were re-transplantation, left graft, auxiliary partial orthotopic liver transplantation, and inadequate medical recording. Preoperative variables were analyzed retrospectively. RESULTS: The overall 3-month survival rate was 92%. In univariate analysis, acute progression of disease, severity of hepatic encephalopathy, Child-Pugh class C, hepatorenal syndrome, use of continuous renal replacement therapy, use of ventilator, intensive care unit (ICU) care before transplantation, and MELD scores > or =35 were identified as potential risk factors. However, only ICU care before transplantation and MELD scores > or =35 were independent risk factors for 3-month mortality after LDLT. Three-month and 1-year patient survival rates for those with no risk factors were 95.5% and 88.6%, respectively. In contrast, patients with at least one risk factor had 3-month and 1-year patient survival rates of 88.4% and 81.1%, respectively, while patients with two risk factors had 3-month and 1-year patient survival rates of 55.6% and 55.6%, respectively. CONCLUSIONS: Patients with both risk factors (ICU care before LDLT and MELD scores > or =35) should be cautiously considered for treatment with LDLT.
