Case Reports
Use of test dose allows early detection of subdural local anesthetic injection with lumbar plexus block.
A 56year-old woman underwent a lumbar plexus block for a revision of a left total hip arthroplasty. During the block procedure, the needle was advanced over the transverse process and isolated quadriceps twitches were elicited. After administering a test dose of 3ml of 1.5% lidocaine, the patient developed loss of sensation in the L3-4 dermatomal distribution that progressed caudally to involve both legs followed by inability to move the left leg. ⋯ The patient was resuscitated with normalization of blood pressure and eventually had full resolution of motor and sensory block. Subdural spread of local anesthetic is a potential complication of lumbar plexus block related perhaps to injection of local anesthetic near dural sleeves of nerve roots. The use of a test dose allows early recognition of subdural injection and may limit consequences of inadvertent subdural spread of local anesthetic.

Observational Study
Gastric regurgitation in patients undergoing gynecological laparoscopy with a laryngeal mask airway: a prospective observational study.
The use of pneumoperitonium and the placement of patients in Trendelenburg position are commonly cited reasons for the potential development of intraoperative regurgitation of gastric contents and the need for an endotracheal tube in laparoscopic surgery. The main objective of the current investigation was to evaluate the presence of regurgitation of gastric contents in the oropharynx of patients having laparoscopic gynecological surgery with a laryngeal mask airway (LMA). ⋯ Our current results suggest that the use of an LMA in healthy patients undergoing laparoscopic gynecological surgery may be safe. Future studies to confirm or refute our findings are warranted.

There has been a gradual decline in the number of case reports published in leading medical journals in recent years. Since case reports are not highly cited they have an adverse effect on the journal impact factor. On the other hand sharing new experiences, challenges, or discoveries with colleagues is essential for medical community. Should case reports be eliminated from the journals or published only in journals devoted to case reports? ⋯ Case reports have been an important source of clinical guidance and scientific insight, and play an important role in medical education. They can be published quickly, providing publication opportunity for juniors and for clinicians who may not have the time or finance to conduct large-scale research. On the other hand some argue, that case reports are irrelevant in current medical practice and education, being at the bottom of the hierarchical ladder of medical evidence. We conclude that case reports should not be done away with but be published in websites and journals like the venue to be launched in 2013 by the International Anesthesia Research Society, devoted entirely to them to meet the need for the publication of interesting cases.
