Randomized Controlled Trial Comparative StudyA comparison between the Airtraq and Macintosh laryngoscopes for routine airway management by experienced anesthesiologists: a randomized clinical trial.
The Airtraq Optical Laryngoscope is a new type of laryngoscope that provides a direct view of the glottis without alignment of the mouth, pharynx and trachea. Data show that it has advantages over the Macintosh laryngoscope. ⋯ The Airtraq laryngoscope is easier to use but it does not have any significant advantages compared with the Macintosh laryngoscope for routine airway management. More studies are needed to evaluate its use in patients with a difficult airway, and in emergency procedures.

Randomized Controlled Trial Comparative StudyComparison of atracurium and "mini-dose" succinylcholine for preventing succinylcholine-induced muscle fasciculations: a randomized, double-blind, placebo-controlled study.
Several drugs have been used to prevent or attenuate succinylcholine- induced muscle fasciculations. There are possible advantages to succinylcholine pretreatment. We designed the present study to compare the effectiveness of atracurium versus "mini-dose" (5 mg) succinylcholine pretreatment for the prevention of muscle fasciculations. ⋯ Our results showed that the incidence and severity of fasciculations were significantly decreased by atracurium pretreatment but not by pretreatment with succinylcholine or placebo (p<0.0001 and p=0.0003 respectively). However, atracurium did not exert significant effects on POM.

Case ReportsAn unusual case of peripartum cardiomyopathy in a parturient with preeclampsia.
Here we report an unusual development of peripartum cardiomyopathy (PPCM) in a parturient woman with preeclampsia. A 36-year-old nulliparous parturient woman underwent elective cesarean section for delivery of twins under spinal anesthesia. Both preoperative workup and past history were unremarkable except for proteinuria and hypertension for 1 week. ⋯ Fortunately, the patient recovered after treatment and was discharged 15 days later. This case illustrates that we should bear in mind the possibility of PPCM if orthopnea develops while delivery is approaching in a parturient with preeclampsia. Echocardiography is helpful for early diagnosis of PPCM.

Case ReportsApplication of a double-lumen tube for one-lung ventilation in patients with anticipated difficult airway.
One-lung ventilation (OLV) is essential in some surgical situations. The use of double- lumen tubes (DLTs) can achieve OLV more quickly and more easily than bronchial blockers. The management of a difficult airway is a challenge for anesthesiologists when, at the same time, OLV is needed for a surgical procedure. ⋯ Nasal intubation of Case 2 was done with fiberoptic-guided intubation with the patient awake. OLV was achieved uneventfully after inserting the DLT directly through the tracheostomy in both cases. We also describe the appropriate use of airway devices for OLV, focusing on patients with an anticipated difficult airway.

Case ReportsDifficult removal of an epidural catheter in the anterior epidural space.
When administering postoperative acute pain services, particularly regarding patient- controlled epidural analgesia, difficulties may occasionally be encountered during removal of the epidural catheter. In this report, we present an instance of difficult removal of epidural catheter in a female patient undergoing open reduction and internal fixation of the femoral neck with patient-controlled epidural analgesia as the means of postoperative pain control. The patient had satisfactory analgesia for 3 days; however, during the removal of the epidural catheter, difficulties were encountered and epidurogram revealed that the epidural catheter had become anchored in the anterior epidural space without kinking or knotting. ⋯ Fortunately, the epidural catheter was removed easily without the need for a guided stylet. We believe that the cause of the difficult removal of the epidural catheter in this case might have resulted from an unusual and unwanted deeper anchorage of the catheter along the anterior epidural space during placement. We also include some discussion on the management of problematic removal.
