Web23 Oct 2024 · A tetanic stimulation (TET) is a single, high-frequency stimulation delivered at 50 Hz for 5 seconds. A strong muscle contraction is evoked and sustained without fade or post-tetanic potentiation in a non-paralyzed patient. Particular caution should be used when employing TET. WebNumerous recent studies have documented that some patients are in fact partially paralyzed for a period of time after anesthesia, sometimes to their detriment. 1 We know that subjective twitch monitoring with a peripheral nerve stimulator is not sufficiently sensitive for detection of clinically significant fade in the train-of-four. 2 …

Web19 Dec 2024 · What is PTC? PTC (post-tetanic count) is the number of responses to single twitch stimulation spaced 1 second apart following high frequency tetanic stimulation (5-second 50 Hz), but why is it actually useful? Post-tetanic count monitoring mode provides a way to quantify deep neuromuscular blockade—when a patient has a TOF Count of 0 [3, 4]. WebStudies have related the reappearance of a single post-tetanic twitch to early diaphragmatic recovery.[2,3] In our case, an extremely deep NMB would have been required to prevent hiccups. Our experience suggests that this could have been avoided through more attentive suction during laparoscopic surgery. Returning the patient to a neutral ...
