OBJECTIVE To evaluate the risk of phrenic nerve injury during ultrasound-guided stellate ganglion block (US-SGB) according to sonoanatomy of the phrenic nerve, and determine a safer posture for needle insertion by assessing its relationship with surrounding structure according to positional change. METHODS Twenty-nine healthy volunteers were recruited and underwent ultrasound in two postures,...

We studied 16 patients with acute lung injury receiving volume-controlled ventilation to assess the relationships between gas exchange and respiratory mechanics before, during, and after 2 h in the prone position. We measured the end-expiratory lung volume (EELV, helium dilution), the total respiratory system (Cst,rs), the lung (Cst,L) and the thoracoabdominal cage (Cst,w) compliances (end-insp...

INTRODUCTION Due to the potential for intramuscular fluid shifts from changing body position, researchers often utilize a 10- to 15-min period of supine rest as a standardizing procedure prior to ultrasound assessment of the lower limbs. However, no previous research has observed the changes in muscle morphological characteristics via ultrasonography of the lower limbs depending on the length o...

Standing up from a supine position is important for physical independence. This study was designed to describe movements within specific body regions used to stand up from a supine position. Another purpose was to identify motor developmental sequences for the upper extremities, lower extremities, and axial region for this rising task. Thirty-two young adults were videotaped while rising from a...

We investigated whether the cerebral (rSO2-C %) and renal (rSO2-R %) tissue oxygenation of preterm infants is altered by repositioning from the supine to semi-upright position for pre-discharge car seat testing. Near-infrared spectroscopy was used to measure rSO2-C and rSO2-R, which were recorded simultaneously with vital signs in 15 preterm infants for 30 minutes in supine, 60 minutes in the s...

Background: The responsibility of the anesthesiologist is to maintain airway patency for better oxygenation. Perhaps the most dangerous incident for the anesthesiologist, are encountering the scenario in which intubation and ventilation in a patient are impossible. The study of mask ventilation is far more limited. The first significant manuscript focused on mask ventilation was published in 20...

The objectives of this study were to verify the influence of a short-duration training session on proximal and distal adjustments at the onset of goal-directed reaching and to verify whether these adjustments change in specificity with the body position trained. Twenty-four infants aged 3-4 months were assessed in supine and reclined during pre and posttraining conditions. During the interval (...

conclusions compared to supine position, semi-fowler’s position is more effective in relieving chemotherapy-induced nausea and vomiting. results the severity, duration, and frequency of nausea and the severity and frequency of vomiting episodes in the control group differed significantly across the nine measurement time-points (p < 0.001). in the experimental group, the severity (p = 0.254) and...

BACKGROUND Delivery room management (DR) of the newly born infant should be performed according to international guidelines, but no recommendations are available for an infant's position immediately after birth. The present study was performed to answer the following questions: 1. How often is DR-management performed in term infants in side position? 2. Is routine DR-management possible in side...

BACKGROUND Prone whole breast irradiation (WBI) leads to reduced heart and lung doses in breast cancer patients receiving adjuvant radiotherapy. In this feasibility trial, we investigated the prone position for whole breast + lymph node irradiation (WB + LNI). METHODS A new support device was developed for optimal target coverage, on which patients are positioned in a position resembling a ph...
