Pernicious placenta previa (PPP) can increase the risk of perioperative complications. During caesarean section in patients with adherent placenta, intraoperative blood loss, hysterectomy rate and transfusion could be reduced by interventional methods. Our study aimed to investigate the influence of maternal hemodynamics control and neonatal outcomes of prophylactic temporary abdominal aortic balloon (PTAAB) occlusion for patients with pernicious placenta previa. ⋯ PTAAB occlusion could be useful in reducing the rate of post-operative uterine artery embolism and the amount of transfusion, and be useful in coping with patients with preoperative vaginal bleeding conditions, so as to reduce the rate of intraoperative applications of vasopressors and the postoperative ICU (intensive care unit) admission. In PPP patients with placenta implantation, central placenta previa and complete placenta previa, we advocate the utilization of prophylactic temporary abdominal aortic balloon placement.

Comparative Study
Labor epidural analgesia versus without labor epidural analgesia for multiparous women: a retrospective case control study.
Labor epidural analgesia (LEA) effectively relieves the labor pain, but it is still not available consistently for multiparous women in many institutions because of their obviously shortened labor length. ⋯ Labor epidural analgesia for the multiparous woman may alter progress of labor, increase postpartum blood loss and lower Apgar scores. Early or late initiation of LEA should be defined as with cervical dilatation of less or more than 3 cm and the different effect should be understand.

Undiagnosed obstructive sleep apnea (OSA) is associated with adverse perioperative outcomes. The STOP-Bang questionnaire is a validated screening tool for OSA. However, its precision may vary among different populations. This study determined the association between high-risk OSA based on the modified STOP-Bang questionnaire and perioperative adverse events. ⋯ Neither modified nor original STOP-Bang was significantly associated with perioperative adverse events. However, a modified STOP-Bang ≥3 can help identify patients at risk of difficult airway, need for oxygen therapy, and ICU admission.

Randomized Controlled Trial
A randomized controlled trial of ultrasound-assisted technique versus conventional puncture method for saphenous venous cannulations in children with congenital heart disease.
The study investigated the success rate of the great saphenous venous catheter placement performed by ultrasound-assisted technique compared with the conventional puncture method in infants and toddlers with congenital heart disease and aimed to assess the efficiency and feasibility of this method within the context of pediatric peripheral venous access. ⋯ The ultrasound-assisted technique improves the saphenous venous cannulation sufficiently in children with difficult peripheral veins. The younger age is associated with a higher likelihood of peripheral venous difficulty. The ultrasound-assisted methods can effectively screen peripheral veins, e.g., selecting thicker diameter peripheral veins, making puncture less uncomfortable, and improving success rates. This method can be used as one of the effective and practical ways of peripheral venipuncture in children, especially in difficult situations. It should be widely applied as one of the alternative ultrasound techniques in the operating room.

Subdural anesthesia and spinal subdural hematoma are rare complications of combined spinal-epidural anesthesia. We present a patient who developed both after multiple attempts to achieve combined spinal-epidural anesthesia. ⋯ All anesthesiologists should be aware of the possibility of SSDH and subdural block when performing neuraxial anesthesia, especially in patients in whom puncture is difficult. Less traumatic methods of achieving anesthesia, such as epidural anesthesia, single-shot spinal anesthesia, or general anesthesia should be considered in these patients. Furthermore, vital signs and neurologic function should be closely monitored during and after surgery.
