Meta Analysis Comparative Study
Comparative efficacy of Neuraxial and general anesthesia for hip fracture surgery: a meta-analysis of randomized clinical trials.
The choice of anesthesia technique remains debatable in patients undergoing surgical repair of hip fracture. This meta-analysis was performed to compare the effect of neuraxial (epidural/spinal) versus general anesthesia on perioperative outcomes in patients undergoing hip fracture surgery. ⋯ In summary, our present study demonstrated that there might be a difference in blood loss between patients receiving neuraxial and general anaesthesia, however, this analysis was not robust to adjustment for multiple testing and therefore at high risk for a type I error. Due to small sample size and enormous inconsistency in the choice of outcome measures, more high-quality studies with large sample size are needed to clarify this issue.

Review Case Reports
Ossification of the cervical anterior longitudinal ligament is an underdiagnosed cause of difficult airway: a case report and review of the literature.
Ossification of the anterior longitudinal ligament (OALL) of the cervical spine is a common, but rarely symptomatic, condition mostly observed in the geriatric population. Although the condition usually requires no intervention, it could lead to a difficult airway and compromise the patient's safety. ⋯ Anesthesiologists should understand that OALL of the cervical spine could cause a difficult airway. However, it is difficult to recognize asymptomatic OALL on the basis of routine airway evaluation guidelines. For susceptible populations, a thorough evaluation of the airway, based on imaging studies and a history of compression symptoms, should be considered whenever possible. In case of unanticipated difficult intubation, anesthesiologists should refer to guidelines for unanticipated difficult airway management and identify OALL of the cervical spine as the cause.

Intraoperative hypotension is associated with increased morbidity and mortality after surgery. We hypothesized that intraoperative hypotension might also be associated with worse long-term survival after cancer surgery. Herein, we analyzed the correlation between intraoperative hyper-/hypotension and overall survival after lung cancer surgery. ⋯ For patients undergoing lung cancer surgery, intraoperative hypotension, but not hypertension, was associated with shortened overall survival.

Review Case Reports
Severe low cerebral oximetry in difficult cardiopulmonary bypass weaning of low body-weight infant: a case report and literature review.
For infants undergoing complex cardiac surgery, hemodynamic management after cardiopulmonary bypass (CPB) is challenging because of severe myocardial edema, vasomotor dysfunction and weak tolerance to a change in blood volume. More importantly, the lack of availability of equipment for advanced monitoring, such as transesophageal echocardiography or transthoracic echocardiography, restricts the accurate assessment of hemodynamics. ⋯ For infants who develop refractory hypotension and failure in SpO2 monitoring during the CPB weaning period, cerebral oximetry provides an index for assessing brain perfusion and valuable guidance for appropriate inotropic treatment.

Comparative Study Observational Study
Accuracy and trending abilities of finger plethysmographic blood pressure and cardiac output compared to invasive measurements during caesarean delivery in healthy women: an observational study.
In women presenting for caesarean section under spinal anesthesia, continuous measurement of circulatory aspects, such as blood pressure and cardiac output, is often needed. At present, invasive techniques are used almost exclusively. Reliable non-invasive monitoring would be welcome, as it could be safer, less uncomfortable, and quick and easy to apply. We aimed to evaluate whether a non-invasive, finger plethysmographic device, the ccNexFin monitor, can replace invasively measured blood pressure in the radial artery, and whether cardiac output measurements from this device can be used interchangeably with measurements from the mini-invasive LiDCO monitor currently in use at our institution. ⋯ We consider the ccNexFin monitor to have sufficient accuracy in measuring mean arterial pressure. The limits of agreement for systolic measurements were wider, and the trending ability compared to invasive measurements was outside the recommended limit. The ccNexFin is not reliable for cardiac output measurements or trend in pregnant women for caesarean delivery under spinal anesthesia.
