Higher preoperative Qp/Qs ratio is associated with lower preoperative regional cerebral oxygen saturation in children with ventricular septal defect.
The relationship between regional cerebral oxygen saturation (rSO2) and the amount of left-to-right shunt in ventricular septal defect (VSD) patients has not yet been investigated. The purpose of this study was to identify the association of preoperative pulmonary to systemic blood flow (Qp/Qs) ratio and preoperative rSO2 in patients with VSD. ⋯ A higher Qp/Qs ratio was associated with a lower preoperative cerebral rSO2 in pediatric patients with VSD.

Cervical erector spinae plane block as a perioperative analgesia method for shoulder arthroscopy: a case series.
Shoulder arthroscopy, a common intervention for severe rotator cuff injuries, is associated with severe postoperative pain. Upon performing cervical erector spinae plane (ESP) blocks at the C7 TP (tip or posterior tip) or the posterior tip of the C6 TP posterior tubercle in six patients undergoing shoulder arthroscopy, sensory block was detectable in congruent cervico-thoracic dermatomes. Effective intraoperative and postoperative analgesia were consistently obtained for all six patients. This preliminary study illustrated that the cervical ESP block can be considered a potential simple regional anesthesia method for providing analgesia during shoulder arthroscopy with low risks of diaphragmatic paresis, upper extremity motor paresis, nerve injury and persistent hypotension.
