Randomized Controlled TrialLaparoscopic-guided psoas blockade as a novel analgesic method during inguinal herniorrhaphy: a clinical trial.
Under laparoscopic guidance, block of ilioinguinal, iliohypogastric, and genitofemoral nerves can be possible with anesthetic injection in the plane between psoas major and the fasciae covering its anterior aspects [laparoscopic-assisted psoas (LAP) blockade]. This observer-blinded trial aimed to compare the opioid-sparing effect of LAP block with transversus abdominis plane (TAP) block after laparoscopic inguinal herniorrhaphy. ⋯ A single injection LAP blockade significantly reduces the post-operative analgesic requirements and provides longer pain relief compared with TAP block after laparoscopic inguinal herniorrhaphy.

Randomized Controlled TrialChloroprocaine 10 mg/ml for low-dose spinal anaesthesia in perianal surgery - a randomised dose finding study.
Low-dose spinal anaesthesia is a safe and reliable anaesthesia technique in outpatient perianal surgery. Regarding its short duration of action and its trend to hyperbaric characteristics, plain chloroprocaine 10 mg/ml seems to be ideal to perform low-dose spinal anaesthesia. The aim of this trial was to determine the optimal dosage of chloroprocaine for this indication. ⋯ Plain chloroprocaine 10 mg/ml can successfully be used for low-dose spinal anaesthesia in perianal outpatient surgery. Regarding the unfavourable motor block and later discharge-times in the 30 mg group on the one hand and the block-failures in the 10 mg group on the other, 20 mg can be recommended as the optimal dose.

Randomized Controlled Trial Multicenter Study Comparative StudyHigher vs. lower haemoglobin threshold for transfusion in septic shock: subgroup analyses of the TRISS trial.
Using a restrictive transfusion strategy appears to be safe in sepsis, but there may be subgroups of patients who benefit from transfusion at a higher haemoglobin level. We explored if subgroups of patients with septic shock and anaemia had better outcome when transfused at a higher vs. a lower haemoglobin threshold. ⋯ In exploratory analyses of a randomized trial in patients with septic shock and anaemia, we observed no survival benefit in any subgroups of transfusion at a haemoglobin threshold of 90 g/l vs. 70 g/l.
