Randomized Controlled Trial Comparative StudyNovel ultrasound-guided inter-semispinal plane block: a comparative pilot study in healthy volunteers.
We previously reported that a novel multifidus cervicis plane (MCP) block could anesthetize the dorsal rami of the cervical spinal nerves. While MCP sonoanatomy is easily detectable in most patients, it is sometimes difficult to recognize the MCP injection plane, especially in elderly patients. Thus, we proposed the inter-semispinal plane (ISP) block as an alternative for the MCP block. ⋯ The anesthetic area ranged from C4 to T2 (3/8; 37.5%), T3 (2/8; 25%), or T4 (3/8; 37.5%) in the MCP block, and from C4 to T1 (1/8; 12.5%), T2 (3/8; 37.5%), T3 (2/8; 25%), or T4 (1/8; 12.5%) in the ISP block. The mean (standard deviation) duration of sensory loss following MCP and ISP blocks was 329 (77) min and 349 (70) min, respectively. Thus, the ISP block may be a reliable alternative to the MCP block.

Correction to: Cerebrovascular CO2 reactivity during isoflurane-nitrous oxide anesthesia in patients with chronic renal failure.
In the original publication of the article, the first sentence was published incorrectly under the section "Patients and preoperative assessment". The correct sentence should read as, "The Yamaguchi University Graduate School of Medicine Ethics Committee for Human Study approved the study protocol (18th August 2004: H16-71)".

Randomized Controlled TrialIntraoperative administration of dexmedetomidine reduced the postoperative catheter-related bladder discomfort and pain in patients undergoing lumbar microdiscectomy.
We aimed to evaluate the effect of the intraoperative dexmedetomidine (DEX) on the incidence and severity of catheter-related bladder discomfort (CRBD) after non-urologic surgery. The secondary aim was to find the correlation between the levels of CRBD and postoperative pain sensation. ⋯ Intraoperative administration of DEX is a safe and effective practice for the prevention of CRBD after lumbar microdiscectomy and can reduce postoperative pain.

Preoperative pulmonary function tests before low-risk surgery in Japan: a retrospective cohort study using a claims database.
Routine preoperative pulmonary function tests (PFTs) are not recommended prior to low-risk surgery because their prognostic value is limited. However, only a few studies have assessed the utilization of healthcare resources regarding preoperative PFTs in a real-world setting. Here, we aimed to assess the prevalence and determinant factors of preoperative PFTs before low-risk surgery in Japan. ⋯ Our analysis found that preoperative PFTs were performed before 72% of low-risk surgeries under general anesthesia. Apart from age, preoperative PFTs were determined primarily by non-medical factors. Additionally, we observed substantial institutional variation in the use of preoperative PFTs.

Randomized Controlled TrialDoes prophylactic ondansetron reduce norepinephrine consumption in patients undergoing cesarean section with spinal anesthesia?
Spinal anesthesia-induced hypotension (SAIH) during cesarean delivery is not rare and frequently leads to materno-fetal discrepancy and collapse. More recently, norepinephrine has been proposed for the prevention and treatment of SAIH with fewer tendencies to decrease heart rate and cardiac output. Ondansetron has been reported to reduce the incidence of SAIH in patients undergoing cesarean section. The aim of the present study was to assess the effect of prophylactic ondansetron on the incidence of SAIH, norepinephrine consumption, and adverse effects. ⋯ Eight milligrams of intravenous ondansetron given 5 min before spinal anesthesia attenuated but did not prevent spinal anesthesia-induced hypotension in parturients undergoing elective cesarean delivery.
