Identification of return of spontaneous circulation during cardiopulmonary resuscitation via pulse oximetry in a porcine animal cardiac arrest model.
In this prospective study we investigated whether the pulse oximetry plethysmographic waveform (POP) could be used to identify return of spontaneous circulation (ROSC) during cardio-pulmonary resuscitation (CPR). Tweleve pigs (28 ± 2 kg) were randomly assigned to two groups: Group I (non-arrested with compressions) (n = 6); Group II (arrested with CPR and defibrillation) (n = 6). Hemodynamic parameters and POP were collected and analyzed. ⋯ With compressions, POP showed a regular compression wave. After defibrillation, ROSC, and continued compressions, a hybrid fluctuation or "envelope" phenomenon appeared in the time domain method and a "double" or "fusion" peak appeared in the frequency domain method, similar to Group I. Analysis of POP using the time and frequency domain methods could be used to identify ROSC during CPR.

Randomized Controlled Trial Comparative StudyCricoid-mental distance-based versus weight-based criteria for size selection of classic laryngeal mask airway in adults: a randomized controlled study.
The optimal size selection of laryngeal mask airway (LMA) based on body weight is not always applicable. This study was prospectively conducted to evaluate the efficacy of cricoid-mental distance-based method versus weight-based method in optimal size selection of LMA in adults. Seventy-four patients (aged from 18 to 65) undergoing ophthalmic surgery were randomly assigned into cricoid-mental (CM) distance-based group or weight-based group to select appropriate size of LMA. ⋯ The overall success rate of LMA insertion in CM distance-based group was slightly increased in comparison with the weight-based group (100% vs. 91.9%, P = 0.240). There were no significant differences in score of fiber-optic view and postoperative pharyngolaryngeal morbidity between both groups (all P > 0.05). CM distance-based criteria is an alternative choice for optimizing size selection of classic LMA in adults.

Randomized Controlled Trial Comparative StudyPatient intermittent epidural boluses (PIEB) plus very low continuous epidural infusion (CEI) versus patient-controlled epidural analgesia (PCEA) plus continuous epidural infusion (CEI) in primiparous labour: a randomized trial.
Epidural maintenance technique for labour analgesia updates constantly. Thanks to infusion pumps, the recently developed programmed intermittent epidural bolus (PIEB) may reduce the use of anesthetic drugs and minimize unintended consequences such as cardio or neurotoxicity. Nevertheless, it is not yet a general practice. ⋯ PIEB group required fewer PCEA boluses. Further studies are needed to determine the best approach for epidural pain management.
