objectives comparing the effects of spontaneous pushing in the lateral position with the valsalva maneuver during the second stage of labor on maternal and fetal outcomes. methods inclusion criteria in this randomized clinical trial conducted in iran were as follows: nulliparous mothers, live fetus with vertex presentation, gestational age of 37 - 40 weeks, spontaneous labor, and no complicatio...

Results: The sample of 8 articles showed that the fastest onset of blockade in pregnant women occurs in the lateral horizontal decubitus position and in the sitting position with legs downwards. Lateral decubitus with elevated head presented insufficient blockade. Lateral position was related to greater comfort, and its maintenance for 15 minutes before the supine position, after infiltration w...

OBJECTIVE The purpose of this study was to investigate endotracheal tube cuff pressure (Pcuff) alteration in patients under mechanical ventilation after changes in position. METHODS All selected patients were initially placed in the 35 degrees semi-Fowler position, with Pcuff adjusted to 20 mmHg, and randomly divided into two groups. Group A, in which patients were moved to the lateral decubi...

OBJECTIVE To assess the effect of uvulopalatopharyngoplasty (UPPP) on positional dependency in patients with obstructive sleep apnea (OSA). DESIGN Retrospective analysis. SETTING Tertiary care university hospital. PATIENTS Ninety-six patients who underwent UPPP because of OSA from June 1, 2004, through July 31, 2008, were included. Both preoperative and postoperative attended full-night p...

PURPOSE To investigate the effect of change of body posture from the supine to the lateral decubitus position on intraocular pressure (IOP) in patients with open-angle glaucoma. DESIGN Prospective, observational case series. METHODS Setting. Institutional. Participants. Forty-four eyes of 22 patients with newly diagnosed bilateral open-angle glaucoma. Observation procedures. IOP was measure...

PURPOSE To investigate the relationship between preferred sleeping position and asymmetric visual field (VF) loss in open-angle glaucoma (OAG) patients. DESIGN Retrospective, cross-sectional study. METHODS Six hundred and ninety-two (692) patients with bilateral normal-tension glaucoma (NTG) or high-tension glaucoma were consecutively enrolled. A questionnaire to determine the preferred sle...

BACKGROUND Post-dural puncture headache (PDPH) is a relatively common complication of lumbar punctures for spinal anesthesia or neurologic diagnosis. For many years, a high number of drugs has been evaluated to treat PDPH, yet there is a minority to prevent this complication. The lateral decubitus position instead of sitting position during lumbar puncture has become an interesting approach bec...

In this research a comprehensive finite element program was developed in order to carry out an elasto perfectly plastic analysis of geogrid reinforcement of a model pavement. Qualitative agreement is seen between the numerical results and experiment. The results indicate the influence of geogrid in reduction of vertical deformation of pavements. It is also seen that for strong subgrade, the opt...
