Fiberoptic-guided intubation after insertion of the i-gel airway device in spontaneously breathing patients with difficult airway predicted: a prospective observational study.

Study Objective: To assess the viability of performing fiberoptic-guided orotracheal intubation through the i-gel airway device previously inserted in spontaneously breathing patients with predicted difficult airway to achieve a patent airway.

Design: Prospective observational study.

Setting: Operating room in a tertiary care hospital.

A comparison of the I-Gel supraglottic device with endotracheal intubation for bronchoscopic lung volume reduction coil treatment.

Study Objective: To compare the use of the I-gel airway with orotracheal intubation (OTI) for bronchoscopic lung volume reduction (BLVR) coil treatment in patients with severe chronic obstructive pulmonary disease (COPD) with heterogeneous emphysema, since it has been proved that supraglottic airways have lower incidence of postoperative respiratory complaints compared to OTI.

Design: A comparative, prospective observational study was designed to assess the use of the I-gel airway compared with the OTI.

Setting: Bronchoscopy room at the University Hospital Fundación Jimenez Diaz, Madrid.

Delayed quadriparesis after an interscalene brachial plexus block and general anesthesia: a differential diagnosis.

Interscalene brachial plexus block has been widely used for upper limb surgery. Different neurological complications related to this technique have been published. We report a case of quadriparesis of delayed onset, without loss of consciousness or cardiopulmonary compromise after an interscalene block and general anesthesia in a seated position.

[Effect of theophylline and theobromine on cell respiration and calcium transport in isolated rat liver mitochondria].

The influence of theophylline and theobromine on cellular respiration and on membrane transport of calcium has been studied in isolated rat liver mitochondria, using oxygen and Ca2+ selective electrodes. A linear decrease in respiratory coefficients, in the total amount and rate of "extra" oxygen consumption induced by ADP is observed with drug concentration. Theobromine does not show any appreciable effect on these respiratory parameters, but this result is similar to that observed with theophylline for the same concentration range.
