Dexmedetomidine suppresses intractable hiccup during anesthesia for cochlear implantation.

We report on the successful use of dexmedetomidine to treat persistent intractable hiccup in a child who underwent cochlear implantation under sevoflurane-fentanyl anesthesia.

Effects of perineural administration of dexmedetomidine in combination with bupivacaine in a femoral-sciatic nerve block.

Background And Aim: Perineural administration of dexmedetomidine, a α2-adrenoceptor agonist, prolongs the duration of analgesia. We hypothesized that adding dexmedetomidine to bupivacaine would prolong postoperative analgesia after below knee surgery.

Materials And Methods: After ethical approval, 60 patients scheduled for below knee surgery under combined femoral-sciatic nerve block were randomly allocated into two groups to have their block performed using bupivacaine 0.

Target-Controlled Infusion of Remifentanil Without Muscle Relaxants Allows Acceptable Surgical Conditions During Thoracotomy Performed Under Sevoflurane Anesthesia.

Objectives: To test the hypothesis that the use of a nonmuscle relaxant anesthetic technique (NMRT) during thoracotomy would be associated with comparable surgical conditions with the standard use of neuromuscular blocking drugs.

Design: A prospective, randomized, single-blind, controlled study.

Setting: A single university hospital.

A comparison of the disconnection technique with continuous bronchial suction for lung deflation when using the Arndt endobronchial blocker during video-assisted thoracoscopy: A randomised trial.

Background: The use of the Arndt endobronchial blocker has not gained widespread acceptance during video-assisted thoracoscopic surgery (VATS) because of its high cost and longer time to operative lung collapse especially in patients with chronic obstructive pulmonary disease (COPD). The use of a ventilator disconnection technique has been shown to produce a comparable degree of lung collapse when used with either a double-lumen tube or an Arndt endobronchial blocker.

Objective: We hypothesised that the use of bronchial suction through the suction port of the endobronchial blocker would be associated with a comparable time to achieve optimum lung collapse as the disconnection technique.

High-frequency jet ventilation using the Arndt bronchial blocker for refractory hypoxemia during one-lung ventilation in a myasthenic patient with asthma.

A novel method in the management of refractory severe hypoxemia during one-lung ventilation (OLV) in a patient who presented with myasthenia gravis, asthma, a symptomatic mediastinal mass, hiatal hernia, and a moderate pericardial effusion is presented. The patient was scheduled for excision of a large anterior mediastinal mass and creation of a pericardial window through a left thoracotomy. One-lung ventilation was achieved using an Arndt bronchial blocker.

Effect of tidal volume on extravascular lung water content during one-lung ventilation for video-assisted thoracoscopic surgery: a randomised, controlled trial.

Background: The use of low tidal volume during one-lung ventilation (OLV) has been shown to attenuate the incidence of acute lung injury after thoracic surgery.

Objective: To test the effect of tidal volume during OLV for video-assisted thoracoscopic surgery on the extravascular lung water content index (EVLWI).

Design: A randomised, double-blind, controlled study.

Right ventricular function during one-lung ventilation: effects of pressure-controlled and volume-controlled ventilation.

Objectives: To test the effects of pressure-controlled (PCV) and volume-controlled (VCV) ventilation during one-lung ventilation (OLV) for thoracic surgery on right ventricular (RV) function.

Design: A prospective, randomized, double-blind, controlled, crossover study.

Setting: A single university hospital.

Changes in cerebral oxygenation in patients with pulmonary dysfunction after lung resection.

Lung resection would be associated with lower jugular bulb oxygen saturation (SjvO₂) values in patients with moderate to severe pulmonary dysfunction. We aimed to study the effects of lung resections on the postoperative changes in SjvO₂, incidence of SjvO₂ < 50%, pulmonary functions, cerebral blood flow equivalent (CBFE), and arterial to jugular difference in oxygen content (AjvDO₂) in the patients with pulmonary dysfunction. Fifty-three patients scheduled for lung resection were allocated on the basis of forced vital capacity (FVC %) and forced expiratory volume in 1 second (FEV(1)%) into the following: good FVC and FEV₁ (n = 14), mild (n = 14), moderate (n = 13), and severe (n = 12) pulmonary dysfunction groups.

Comparative study of the non-dependent continuous positive pressure ventilation and high-frequency positive-pressure ventilation during one-lung ventilation for video-assisted thoracoscopic surgery.

The application of volume controlled high-frequency positive-pressure ventilation (HFPPV) to the non-dependent lung (NL) may have comparable effects to continuous positive-airway pressure (CPAP) on the surgical conditions during one-lung ventilation (OLV) for video-assisted thoracoscopic surgery (VATS). After local Ethics Committee approval and informed consent, we randomly allocated 30 patients scheduled for elective VATS after the first 15 min of OLV to ventilate the NL with CPAP of 2 cm H(2)O (NL-CPAP(2)) and HFPPV using tidal volume 2 ml/kg, inspiratory to expiratory ratio <0.3 and respiratory rate 60/min (NL-HFPPV) for 30 min, each in a randomized crossover order.
