Introduction:
sedation is a key component for the improvement of sedation quality. A correct administration requires appropriate training. We performed a study to compare sedation effectiveness, safety and patient satisfaction when administered by gastroenterologists, with and without specific training.
Methods:
a training program enrolled a group of gastroenterologists (trained group, n = 4) and their results were compared to those from a non-trained group (n = 3). ASA 1-3 patients who had undergone sedation by a gastroenterologist using midazolam and fentanyl were included over a period of 30 months. Safety was assessed in terms of the complication rate, effectiveness was assessed via the rate of completed endoscopic procedures and patient satisfaction was evaluated via a phone interview the day after the procedure.
Results:
a total of 3,475 patients were sedated by gastroenterologists during the study period. Significant differences were found that favored the trained group for completed procedures (5.6% vs 8.9%). A lower rate of excessive sedation (1.3% vs 8.61%), hypoxemia (0.72% vs 2.49%) and post-procedural pain (1.8% vs 4.3%) were also achieved. Patient satisfaction surpassed 99.5% and there were no significant differences between groups.
Conclusions:
our sedation training program improved the effectiveness and safety outcomes when compared to sedation administered by gastroenterologists without this specific training.

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...

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...
