The model for end-stage liver disease (MELD) score is associated with the severity of liver failure in transplant patients. This study examined whether life-threatening stress factors during liver transplantation differed according to the patients' preoperative MELD scores. Forty-four patients who underwent living donor liver transplantation were divided into a high MELD group (MELD score ≥ 20) (n = 25) and a low MELD group (MELD score < 20) (n = 19). ⋯ The systemic vascular resistance index was significantly lower in the high MELD group than in the low MELD group at all time points. The oxygen utility index and the oxygen extraction ratio were all significantly lower in the high MELD group than in the low MELD group only at the preanhepatic stage and not at later stages of surgery. Intraoperative transfusion volume and the severity of metabolic acidosis were not associated with the preoperative MELD score.

The Bowel Function Index for evaluating constipation in pain patients: definition of a reference range for a non-constipated population of pain patients.
Opioid-induced constipation (OIC) is a severe, persisting side-effect of opioid therapy. The Bowel Function Index (BFI(a), numerical analogue scale 0 - 100), calculated as the mean of three variables (ease of defaecation, feeling of incomplete bowel evacuation, and personal judgement of constipation) was developed to evaluate bowel function in opioid-treated patients with pain. This clinician-administered tool allows easy measurement of OIC from the patient's perspective. ⋯ The BFI scores were assessed and compared with those of patients with confirmed OIC obtained from two previously published trials. Results were analysed and a reference range of BFI values of 0 - 28.8, into which 95% of non-constipated chronic pain patients fell, was defined. This permits discrimination between chronic pain patients with, or without, constipation.

Randomized Controlled Trial
Intravenous lidocaine for effective pain relief after inguinal herniorrhaphy: a prospective, randomized, double-blind, placebo-controlled study.
This prospective, randomized, double-blind, placebo-controlled study evaluated the effectiveness of intravenous lidocaine to reduce post-operative pain in 64 inguinal herniorrhaphy patients. Intravenous bolus injection of 1.5 mg/kg lidocaine followed by a continuous lidocaine infusion of 2 mg/kg per h was randomly assigned to 32 patients (lidocaine group) and intravenous normal saline bolus injection followed by infusion of normal saline was assigned to 32 other patients (control group). ⋯ Total fentanyl consumption (patient-controlled plus investigator-controlled rescue administration) and the total number of button pushes were significantly lower in the lidocaine group than in the control group. It is concluded that intravenous lidocaine injection reduced post-operative pain after inguinal herniorrhaphy, is easy to administer and may have potential to become routine practice for this type of surgery.

Randomized Controlled Trial Comparative Study
The effect of ulinastatin on postoperative blood loss in patients undergoing open heart surgery with cardiopulmonary bypass.
This prospective, randomized, double-blind study evaluated the effect of ulinastatin on postoperative blood loss and transfusion requirements of patients undergoing open-heart surgery with cardiopulmonary bypass (CPB) and aortic cross-clamping (ACC). CPB and ACC produce variable systemic inflammatory reactions that are associated with multiorgan dysfunction via leucocytes, especially polymorphonuclear neutrophils (PMNs). PMNs increase blood loss and transfusion requirements. ⋯ There were no statistically significant between-group differences in postoperative blood loss and transfusion requirements. Ulinastatin caused a non-significant decrease in duration of intubation. Patients who received ulinastatin had significantly shorter ICU stays than control patients.

Randomized Controlled Trial Comparative Study
The effects of colloid pre-loading on thromboelastography prior to caesarean delivery: hydroxyethyl starch 130/0.4 versus succinylated gelatine.
This prospective, randomized, double-blind study compared the effects on thromboelastography (TEG) of pre-loading with two different colloid fluids prior to spinal anaesthesia for caesarean section. Healthy full-term parturients received either 500 ml 6% hydroxyethyl starch 130/0.4 (HES, n = 25) or 500 ml 4% succinylated gelatine (GEL, n = 25) prior to spinal anaesthesia. TEG parameters including reaction time (r-time), clot formation time (k-time), clot formation rate (α-angle) and maximum amplitude (MA) were measured immediately before and after pre-loading. ⋯ The α-angle was significantly decreased after pre-loading with HES but not with GEL. No significant differences in k-time were induced pre-loading. In conclusion, pre-loading with HES or GEL was associated with a mild hypocoagulable effect in healthy parturients presenting for elective caesarean section; however, all TEG parameters in both groups remained within or very close to the normal range after pre-loading.
