Remimazolam (CNS 7056) is a new drug innovation in anesthesia. It combines the properties of two unique drugs already established in anesthesia - Midazolam and remifentanil. It acts on GABA receptors like midazolam and has organ-independent metabolism like remifentanil. ⋯ Unlike most rapidly acting intravenous sedatives available presently, the propensity to cause apnea is very low. Availability of a specific antagonist (flumazenil) adds to its safety even in cases of overdose. The present review discusses remimazolam's potential as a new drug in anesthesia along with the presently available literary evidence.

Major lower limb nerve blocks are relatively safe techniques. However, their efficacy for hip hemiarthroplasty is unknown. The objective of this study was to determine the effectiveness of combined femoral, sciatic, obturator and lateral femoral cutaneous (LFC) nerve blocks in providing adequate anesthesia for hip hemiarthroplasty. ⋯ The combined femoral, sciatic, obturator and LFC nerve blocks in addition to local infiltration at the proximal site of skin incision could provide adequate anesthesia for hip hemiarthroplasty. Light sedation before reduction of the prosthetic femur head back into the hip socket is advisable.

Placement of laryngeal mask airway (LMA) is a blind procedure without requiring laryngoscopy. The reported success rate for LMA insertion at the first attempt is almost 95%; however, many functioning LMAs may not be in an ideal anatomic place. It seems that disposable LMAs have more stable cuff pressure compared to reusable LMAs; therefore, Anesthesiologists should bear in mind this fact when using reusable LMAs to achieve a proper sealing and safe airway management. In this report, we introduced a case with malfunction of LMA cuff during the airway management.

Different methods and many drugs have been used to control the post-operative pain. In this study, we evaluate the role of gabapentin premedication and/or dexamethasone in management of post-operative pain following adenotonsillectomy in children. ⋯ Gabapentin 10 mg/kg premedication combined with intra-operative dexamethasone 0.15 mg/kg prolongs the post-operative analgesia following adenotonsillectomy in children and decreases the amount of pethidine used post-operatively with no reported adverse effects or increase in the incidence of post-operative bleeding.
