Effect of pressure support level, patient's effort, and lung mechanics on phase synchrony during pressure support ventilation.
Pressure support ventilation (PSV) is used to encourage spontaneous breathing and facilitate weaning. During PSV, duration of the breath is not set, but controlled by the patient, and influenced by some ventilator settings. There is no guarantee that the PS breathe will match start and end of patient's breathe. Indeed, patient-ventilator breath mismatching during PSV is the rule, not the exception. ⋯ This study delineates direction of effect for certain individual variables on patient-ventilator synchrony. Results of this study should help clinicians understand the complexity of synchrony issue.

The incidence of postoperative residual curarization following the use of intermediate-acting muscle relaxants and related factors.
To evaluate the incidence of residual curarization (RC) and related risk factors in the early and late postoperative periods in patients receiving general anesthesia with intermediate-acting muscle relaxants. ⋯ Reversal use was shown to reduce residual effects of intermediate-acting muscle relaxants in early recovery period, whereas risk of RC in 30 min in PACU was shown to increase with repeated doses of muscle relaxants.

Randomized Controlled TrialIs unilateral spinal anesthesia superior to bilateral spinal anesthesia in unilateral inguinal regional surgery?
Unilateral spinal anesthesia is performed to provide restriction of sensory and motor block. ⋯ The time to reach sensory and motor blocks for unilateral spinal anesthesia could provide an advantage over bilateral spinal anesthesia in inguinal region operations.

Short beveled sharp cutting needle is superior to facet tip needle for ultrasound-guided rectus sheath block in children with umbilical hernia: a case series.
The most common peripheral nerve blocks used in umbilical hernia repair are rectus sheath block and regional block (caudal block). Ultrasound guidance of peripheral nerve blocks has reduced the number of complications and improved the quality of blocks. The aim of this study is to assess the post rectus sheath block pain relief in pediatric patients coming for umbilical surgery, and to evaluate the easiness of soft tissue puncture and ultrasonic appearance of two different needle types. ⋯ Ultrasound guidance enables performances of an effective rectus sheath block for umbilical hernia in the lateral edge of the rectus muscle. Use of the sharp short beveled needle of 22 gauge intravenous (IV) cannula stylet provides easy, less traumatic skin and rectus muscle penetration and better needle visualization by the ultrasound.

Teaching ultrasound procedural skills-low cost phantoms and animal models.
Acquiring the necessary cognitive and psychomotor skills to perform ultrasound guided procedures may require initial training. Growing evidence shows that simulation can help in the acquisition of procedural skills. ⋯ In this study we have described several new phantoms and animal models that are inexpensive, easy to assemble and allow a rapid change of targets. Such phantoms can provide an ideal initial learning opportunity in a zero-risk environment.
