Preoperative using of anatomical landmarks detects potentially difficult laryngoscopies. The main object of the present study was to evaluate the predictive power of Extended Mallampati Score (EMS) in comparison with modified Mallampati test (MMT), the ratio of height to thyromental distance (RHTMD) and the Upper-Lip-Bite test (ULBT) in isolation and combination. ⋯ EMS predicted difficult laryngoscopy better than MMT while both ULBT and RHTMD had more power than EMS and MMT in this regard. ULBT and RHTMD had similar predictive value for prediction of difficult laryngoscopy in general population.

Intraoperative fluid management of the patients who had undergone neurosurgery presents special challenges for the anesthesiologist. In this study, we aimed to compare the effects of two fluid combinations (half-normal + bicarbonate with saline + Ringer's lactate) on brain relaxation, and acid, base, and hemodynamic balance in patients undergoing elective craniotomy surgery. ⋯ These two fluids did not show any significant differences in the studied variables in this research.

Nasal cannula, beside administering low-flow therapy, showed the capability for the administration of continuous positive airway pressure (CPAP) through high-flow nasal cannula (HFNC). Meeting specific physical criteria of 100% relative humidity (RH) and temperature of 37(°)C are the basic interventional requirements to administer oxygen for the newborns through a nasal cannula. Recently, two systems, MR850 and PMH7000, received the Food and Drug Administration (FDA) approval to administer heated, humidified HFNC (HHHFNC). These systems are evaluated in this study based on their humidifying and heating capabilities. ⋯ Although the records of temperature and RH in the PMH7000 system was lower than the records from the MR850 system, no clinical priority was observed for respiratory support with HHHNFC in the two systems.

1,2 ICSRA, introduced by Aidembery et al., is a well-established technique, with up to 100% union rate among different studies. The purpose of our study was to evaluate the outcome of scaphoid nonunion undergoing 1,2 ICSRA bone graft in Iran. ⋯ 1,2 ICSRA is a proper pedicle of vascularized bone graft due to the ease of visibility and dissection. The functional results and union rates were satisfactory in our study.

Post-operative shivering is an unpleasant complication that various drugs are used to prevent and treat. It is tried to advice a suitable drug with the least side-effects. This study was carried out to examine the effect of intravenous Apotel on the post-operative shivering and core and peripheral body temperature. ⋯ Given the beneficial effects of Apotel in post-operative shivering and pain reduction, using the drug as a pre-drug is recommended in patients undergoing surgery with general anesthesia.
