Sevoflurane attenuates brain damage through inhibiting autophagy and apoptosis in cerebral ischemia‑reperfusion rats.

The present study aimed to investigate the effects of sevoflurane post‑conditioning in a rat brain cerebral ischemia‑reperfusion (I/R) model and examine its possible mechanism. Rats were randomly divided into six groups: Sham control group (Sham), I/R group, sevoflurane group (Se), Toll‑like receptor‑4 (TLR4) inhibitor group (Tak‑242), nuclear factor (NF)‑κB inhibitor group (QNZ) and Sevoflurane post‑conditioning combined with TLR4‑NF‑κB signaling pathway inhibitor group (Se + Tak‑242). Morris water maze test and tetrazolium chloride staining were used to investigate the I/R injury.

Intraoperative and postoperative infusion of dexmedetomidine combined with intravenous butorphanol patient-controlled analgesia following total hysterectomy under laparoscopy.

The present prospective, randomized, double-blinded, controlled study aimed to investigate the efficacy and safety of dexmedetomidine (DEX) combined with butorphanol for patient-controlled intravenous analgesia (PCIA) following total laparoscopic hysterectomy. A total of 88 patients undergoing total laparoscopic hysterectomy and receiving postoperative PCIA were divided into two groups following surgery. Patients received DEX 0.
