To investigate the therapeutic effects of a novel fluid resuscitation protocol (early fluid resuscitation plus 2% hydrogen inhalation) on acute kidney injury during septic shock induced by lipopolysaccharide in rats. ⋯ Early fluid resuscitation plus 2% hydrogen inhalation provided more protection against AKI during septic shock.

This study was to determine the optimal dosage of ondansetron for preventing maternal hypotension during cesarean delivery. ⋯ The optimal dose of ondansetron preloading was 4 mg during cesarean delivery.

Case Reports
Surgical treatment and radiotherapy of epidermoid cyst with malignant transformation in cerebellopontine angle.
We report surgical treatment and radiotherapy of an extremely rare case of malignant epidermoid cyst located in cerebellopontine angle. MRI and CT demonstrated the lesion with partial enhancement and calcification. During operation, we found the tumor attached tightly to surrounding tissue. ⋯ With adjuvant radiotherapy, the patient underwent excellent recovery, and follow-up MRI demonstrated no obvious residue or recurrence of the tumor. Malignant epidermoid cyst can be diagnosed radiologically in combination with clinical presentation. Maximal removal plus adjuvant radiotherapy is the treatment of choice, although the general prognosis of it is poor.

A 64-yr-old man was admitted because of repeated pneumonia. Both fiberoptic bronchoscopy and esophagoscopy revealed a large tracheoesophageal fistula (15 mm) in the right posterior trachea 1 cm beyond the carina. ⋯ We took advantage of laryngeal mask airway to insert the fiberoptic bronchoscope to guide the stent placement. Our method of sealing a large tracheoesophageal fistula with LMA under total intravenous anesthesia was successful.

Managing ventilation and oxygenation during laparoscopic procedures in severely obese patients undergoing weight loss surgery presents many challenges. Pressure-controlled ventilation, volume-guaranteed (PCV-VG) is a dual-control mode of ventilation and an alternative to pressure (PC) or volume (VC) controlled ventilation. PCV-VG features a user-selected tidal volume target, that is auto-regulated and pressure controlled. We hypothesized that PCV-VG ventilation would provide improved oxygenation and ventilation during laparoscopic bariatric surgery with a lower peak inflating pressure (PIP) than either PC or VC ventilation. ⋯ In adolescents and young adults undergoing laparoscopic bariatric surgery, PCV-VG and PC were superior to VC ventilation in their ability to provide ventilation with the lowest PIP.
