ABSTRACT
Purpose@#With an increase in the aging population, the number of patients with degenerative spinal diseases undergoing surgery has risen, as has the incidence of postoperative delirium. This study aimed to investigate the risk factors affecting postoperative delirium in older adults who had undergone spine surgery and to identify the associated biomarkers. @*Methods@#This study is a prospective study. Data of 100 patients aged ≥ 70 years who underwent spinal surgery were analyzed. Demographic data, medical history, clinical characteristics, cognitive function, depression symptoms, functional status, frailty, and nutritional status were investigated to identify the risk factors for delirium. The Confusion Assessment Method, Delirium Rating Scale-R-98, and Nursing Delirium Scale were also used for diagnosing deliri-um. To discover the biomarkers, urine extracellular vesicles (EVs) were analyzed for tau, ubiquitin carboxy-terminal hydrolase L1 (UCH-L1),neurofilament light, and glial fibrillary acidic protein using digital immunoassay technology. @*Results@#Nine patients were excluded, and data obtained from the remaining 91 were analyzed. Among them, 18 (19.8%) developed delirium. Differences were observed between partici-pants with and without delirium in the contexts of a history of mental disorder and use of benzodiazepines (p = .005 and p = .026, respectively). Tau and UCH-L1—concentrations of urine EVs—were comparatively higher in participants with severe delirium than that in partici-pants without delirium (p = .002 and p = .001, respectively). @*Conclusion@#These findings can assist clinicians in accurately identifying the risk factors before surgery, classifying high-risk patients, and predicting and detecting delirium in older patients. Moreover, urine EV analysis revealed that postoperative delirium following spinal surgery is most likely associated with brain damage.
ABSTRACT
Purpose@#Perioperative fluid management in kidney transplant recipients is crucial to supporting the fluid, acid-base, and electrolyte balance required for graft perfusion. However, the choice of intraoperative crystalloids in kidney transplantation remains controversial. We conducted a single-center retrospective cohort study to evaluate the impact of intraoperative fluids on acidbase and electrolyte balance and graft outcomes. @*Materials and Methods@#We included 282 living donor kidney transplant recipients from January 2010 to December 2017. Patients were classified into two groups based on the type of intraoperative crystalloids used (157 patients in the half saline group and 125 patients in the balanced crystalloid solutions group, Plasma-lyte). @*Results@#Compared with the half saline group, the Plasma-lyte group showed less metabolic acidosis and hyponatremia during surgery. Hyperkalemia incidence was not significantly different between the two groups. Changes in postoperative graft function assessed by blood urea nitrogen and creatinine were significantly different between the two groups. Patients in the Plasma-lyte group exhibited consistently higher glomerular filtration rates than those in the half saline group at 1 month and 1 year after transplantation after adjusting for demographic differences. @*Conclusion@#Intraoperative Plasma-lyte can lead to more favorable results in terms of acid-base balance during kidney transplantation. Patients who received Plasma-lyte showed superior postoperative graft function at 1 month and 1 year after transplantation.Further studies are needed to evaluate the superiority of intraoperative Plasma-lyte over other types of crystalloids in relation to graft outcomes.

Opioid-induced chest wall rigidity is an uncommon complication of opioids. Because of this, it is often difficult to make a differential diagnosis in a mechanically ventilated patient who experiences increased airway pressure and difficulty with ventilation. A 76-year-old female patient was admitted to the intensive care unit (ICU) after surgery for periprosthetic fracture of the femur neck. On completion of the surgery, airway pressure was increased, and oxygen saturation fell below 95% after a bolus dose of fentanyl. After ICU admission, the same event recurred. Manual ventilation was immediately started, and a muscle relaxant relieved the symptoms. There was no sign or symptom suggesting airway obstruction or asthma on physical examination. Early recognition and treatment should be made in a mechanically ventilated patient experiencing increased airway pressure in order to prevent further deterioration.

Neurological complications following liver transplantation are more common than after other organ transplants. These complications include seizure in about 8% of cases, which is associated with morbidity and mortality. Seizure should be treated immediately, and the process of differential diagnosis has to be performed appropriately in order to avoid permanent neurologic deficit. We herein report a case of status epilepticus after liver transplantation. The status epilepticus was treated promptly and the cause of seizure was assessed. The patient was discharged without any complication.

A 46-year-old female patient was admitted to the intensive care unit (ICU) after liver transplantation. About an hour later after the ICU admission, she had no pupillary light reflex. Both pupils were also fixed at 5 mm. Patients who undergo liver transplantation are susceptible to neurologic disorders including hepatic encephalopathy, thromboembolism and intracranial hemorrhage. Abnormal pupillary light reflex usually indicates a serious neurologic emergency in these patients; however, benign neurologic disorders such as peripheral autonomic neuropathy or Holmes-Adie syndrome should also be considered. We experienced a case of fixed pupillary light reflex after liver transplantation diagnosed as peripheral autonomic neuropathy.

Transfusion-related acute lung injury (TRALI) was introduced in 1983 to describe a clinical syndrome seen within 6 h of a plasma-containing blood products transfusion. TRALI is a rare transfusion complication; however, the FDA has suggested that TRALI is the leading cause of transfusion-related mortality. Understanding the pathogenesis of TRALI will facilitate adopting preventive strategies, such as deferring high plasma volume female product donors. This review outlines the clinical features, pathogenesis, treatment, and prevention of TRALI.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is administered for a few days after lung transplantation (LTx) in recipients who are expected to have early graft dysfunction. Despite its life-saving potential, immediate postoperative ECMO has life-threatening complications such as postoperative bleeding. We investigated the risk factors related to the use of immediate postoperative ECMO. METHODS: We retrospectively reviewed the records of 60 LTx patients who were at our institution from October 2012 to May 2015. Perioperative variables associated with postoperative ECMO were compared between the two groups. RESULTS: There were 26 patients who received postoperative ECMO (ECMO group) and 34 patients who did not (control group). Multivariate regression analysis revealed preoperative ECMO (odds ratio [OR] 12.55, 95% confidence intervals [CI] 1.34 - 117.24, p = 0.027) and lower peripheral pulse oxymetry saturation (SpO2) at the end of surgery (OR 0.71, 95% CI 0.54 - 0.95, p = 0.019) were independent risk factors for postoperative ECMO in LTx patients. The incidences of complications, such as re-operation, tracheostomy, renal failure and postoperative atrial fibrillation, were higher in the ECMO group. There was no difference in the duration of postoperative intensive care unit stay or postoperative 30-day mortality between the two groups. CONCLUSIONS: The preoperative ECMO and lower SpO2 at the end of surgery were associated with postoperative ECMO. Further, postoperative adverse events were higher in the ECMO group compared with the control group. This study suggests that determination of postoperative ECMO requires careful consideration because of the risks of postoperative ECMO in LTx patients.

PURPOSE: Emergence agitation (EA) is frequently observed in children undergoing general anaesthesia. This study tested whether the addition of an intra-operative low-dose infusion of dexmedetomidine to fentanyl treatment reduced the incidence of emergence delirium following desflurane anesthesia in children undergoing strabismus surgery. MATERIALS AND METHODS: A total of 96 children (1-5 years old) undergoing strabismus surgery were enrolled. Anaesthesia was induced with propofol and maintained with desflurane. After induction, fentanyl (1 microg/kg) was administered to all children. During surgery, patients were infused with 0.2 microg/(kg.h)-1 dexmedetomidine (Group FD, n=47) or normal saline (Group F, n=47). Postoperative objective pain score (OPS), Paediatric Agitation and Emergence Delirium (PAED) score, and EA score were documented every 10 minutes in the post-anaesthesia care unit. RESULTS: There were no significant differences between the two groups in demographic characteristics and haemodynamic changes. The mean values of maximum EA, maximum PAED, and maximum OPS score were significantly lower in Group FD than in Group F at 0, 10, and 20 minutes after arrival at the post-anaesthesia care unit (p<0.001). The frequency of fentanyl rescue was lower in Group FD than in Group F (p<0.001). The incidence of severe EA was significantly lower in Group FD than in Group F (12.8% vs. 74.5%, p<0.001). CONCLUSION: Intra-operative low-dose infusion of dexmedetomidine in addition to fentanyl reduces EA following desflurane anaesthesia in children undergoing strabismus surgeries.

BACKGROUND: Unlike other diseases, the management of sepsis has not been fully integrated in our daily practice. The aim of this study was to determine whether repeated training could improve compliance with a 6-h resuscitation bundle in patients with severe sepsis and septic shock. METHODS: Repeated education regarding a sepsis bundle was provided to the intensive care unit and emergency department residents, nurses, and faculties in a single university hospital. The educational program was led by a multidisciplinary team. A total of 175 adult patients with severe sepsis or septic shock were identified (88 before and 87 after the educational program). Hemodynamic resuscitation bundle and timely antibiotics administration were measured for all cases and mortality at 28 days after sepsis diagnosis was evaluated. RESULTS: The compliance rate for the sepsis resuscitation bundle before the educational program was poor (0%), and repeated training improved it to 80% (p < 0.001). The 28-day mortality was significantly lower in the intervention group (16% vs. 32%, p = 0.040). Within the intervention group, patients for whom the resuscitation bundle was successfully completed had a significantly lower 28-day mortality than other patients (11% vs. 41%, p = 0.004). CONCLUSIONS: Repeated education led by a multidisciplinary team and interdisciplinary communication improved the compliance rate of the 6-h resuscitation bundle in severe sepsis and septic shock patients. Compliance with the sepsis resuscitation bundle was associated with improved 28-day mortality in the study population.
