Acetazolamide identified patients with reduced vasomotor reactivity who appeared to have preserved CO2 reactivity. Acetazolamide testing may be useful in the assessment of cerebral hemodynamics. However, further investigations are necessary to assess the clinical utility of these tests.

The present data demonstrated that the coronary aneurysm could give rise to a small decline of pressure along the artery. Since no aneurysm demonstrated a fractional flow reserve under 0.75, a simple aneurysm would not cause coronary ischaemia by itself. However, it could trigger a coronary ischaemia in case of multiple coronary aneurysms and a coronary aneurysm with mild stenosis.

Ultrasound-guided rectus sheath block is a quicker way to control postoperative pain for pediatric patients undergoing laparoscopic extraperitoneal closure than local anesthetic infiltration, and thus may provide a clinical benefit.

Background: There has been increasing attention regarding quadratus lumborum block (QLB) and erector spinae plane block (ESPB) as effective truncal blocks. There have been reports of combined QLB and ESPB usage in hip surgery resulting in a symbiotic increase in effectiveness. However, there have been no reports regarding robotassisted partial nephrectomy (RAPN), which requires multiple port holes ranging from near the xiphoid process to below the umbilicus. We hypothesized that the combined use of QLB and ESPB was an option for anesthesia and analgesia during RAPN. Case presentation: Anterior QLB and ESPB were applied to two patients undergoing scheduled RAPN. With intravenous patient-controlled analgesia, the post-surgery numerical rating scale scores were < 3/10 at rest and < 5/10 upon movement, throughout the perioperative time. Conclusions: The combination of QLB and ESPB could be an option for the postoperative analgesia in RAPN.
