Bispectral index monitoring system (BIS) is one of the several systems used to measure the effects of anaesthetic and sedative drugs on the brain and to track changes in the patient's level of sedation and hypnosis. BIS monitoring provides information clinically relevant to the adjustment of dosages of sedating medication. It can help the nursing personnel in preventing under- and over sedation among intensive care unit (ICU) patients. ⋯ There exists an awareness among the critical care nursing staff in our institution regarding BIS and its clinical implications. Its use in the critical care setting may benefit the patients in terms of providing optimal sedation.

Mixed drugs poisoning (MDP) is common in the emergency departments. Because of the limited number of intensive care unit beds, recognition of risk factors to divide the patients into different survival groups is necessary. Poisoning due to ingestion of different medications may have additive or antagonistic effects on different parameters included in the scoring systems; therefore, the aim of the study was to compare applicability of the different scoring systems in outcomes prediction of patients admitted with MDP-induced coma. ⋯ The GCS(24), APACHE II(24), MAS(24), and APACHE II(0) scoring systems seem to predict the outcome in comatose patients due to MDP more accurately. GCS and MAS may have superiority over the others in being easy to perform and not requiring laboratory data.

Congenital afibrinogenemia is a very rare autosomal recessive disorder, results from mutation that affects plasma fibrinogen concentration. It is frequently associated with bleeding diathesis of varying severity. We describe the case of a 10-year-old child diagnosed of congenital afibrinogenemia who presented to hospital with subperiosteal haematoma and was posted for incision and drainage. ⋯ Appropriate amount of cryoprecipitate were transfused pre-operatively to the child. Individuals with congenital afibrinogenemia should be managed by a comprehensive bleeding disorder care team experienced in diagnosing and managing inherited bleeding disorders. Anaesthesiologist, surgeons and haematologist should work like a unit to manage the surgical emergencies.

Inguinal hernia repair can be performed under satisfactory anaesthetic conditions using general, regional and peripheral nerve block anaesthesia. Unilateral spinal anaesthesia provides optimal anaesthesia, with stable haemodynamics and minimal adverse events. The paravertebral block, being segmental in nature, can be expected to produce some advantages regarding haemodynamic stability and early ambulation and may be a viable alternative. ⋯ Both the paravertebral block and unilateral spinal anaesthesia are effective anaesthetic techniques for uncomplicated inguinal hernia repair. However, the paravertebral block can be an attractive alternative as it provides early ambulation and prolonged postoperative analgesia with minimal adverse events.

Many molecules can exist as right-handed and left-handed forms that are non-superimposable mirror images of each other. They are known as enantiomers or substances of opposite shape. Such compounds are also said to be chiral (Greek chiros meaning 'hand'). ⋯ The other enantiomer can have undesirable properties, have different therapeutic activities or be pharmacologically inert. Specific examples of application of chirality in anaesthetic drugs include inhalational general anaesthetics (e.g. isoflurane), intravenous anaesthetics (e.g. etomidate, thiopentone), neuromuscular blocking agents (e.g. cisatracurium), local anaesthetics (e.g. ropivacaine and levobupivacaine) and other agents (e.g. levosimendan, dexmedetomidine, L-cysteine). In the recent advances, chirality study has not only helped new drug development as mentioned above, but has also contributed in a more profound way to the understanding of the mechanism of anaesthesia and anaesthetic drugs.
