Randomized Controlled TrialInvestigation of the analgesic effects of rhomboid intercostal and pectoral nerve blocks in breast surgery.
The objective of this study was to examine the hypothesis that the opioid consumption of patients who receive a rhomboid intercostal block (RIB) or a pectoral nerve (PECS) block after unilateral modified radical mastectomy (MRM) surgery is less than that of patients who receive local anesthetic infiltration. ⋯ Compared to local anesthetic infiltration, the RIB and PECS blocks applied as part of multimodal analgesia in MRM surgery reduced opioid consumption in the first 24 h and improved the quality of recovery in the early period.

Changes in oxygen supply-demand balance during induction of general anesthesia: an exploratory study using remimazolam.
This study was performed to evaluate the changes in oxygen supply-demand balance during induction of general anesthesia using an indirect calorimeter capable of measuring oxygen consumption (VO2) and carbon dioxide production (VCO2). ⋯ General anesthetic induction with remimazolam decreased VO2, VCO2, and DO2.

Association between general anesthesia in early childhood and neurodevelopment up to 4 years of age: the Japan Environment and Children's Study.
The effects of general anesthesia on neurodevelopment in children remain controversial. We explored the relationship between general anesthesia and neurodevelopment in children participating in the Japan Environment and Children's Study (JECS). ⋯ This study suggests that general anesthesia administration before age 1 is associated with neurodevelopmental delay during 1-4 years of age. The risk of general anesthesia after age 1 may be small.

The key to success in blocking lateral cutaneous branches with re-modified thoracoabdominal nerves block through perichondrial approach: a newly discovered space between the endothoracic fascia, diaphragm, and costodiaphragmatic recess.
This study aimed to determine whether the administration of a modified thoracoabdominal nerves block through perichondrial approach (M-TAPA) could result in the blockade of the lateral cutaneous branches. This study focused on a newly discovered anatomical space/plane adjacent to the M-TAPA plane, which we termed "space between the endothoracic fascia, diaphragm, and costodiaphragmatic recess: SEDIC." ⋯ Our study revealed the presence of the SEDIC adjacent to the M-TAPA plane. Administration of local anesthetics into the SEDIC, named re-modified TAPA, may have the potential to enhance the analgesic effect in the abdominal region.
