Nonobstetric emergencies are frequent during pregnancy. The emergency physician must be knowledgeable regarding the physiological changes related to pregnancy, and must evaluate the benefit/risk ratio of any medication given to the mother. Though maternal side-effects are easy to predict, the fetal risk remains difficult to evaluate as medications are numerous and clinical evidence scarce. For analgesia as for sedation, the choice will depend on both the clinical context of the patient, the desired objective, and the assumed fetal risk.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Barbiturates
Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
