- Public TitleThe BREATH study
- Scientific TitleEffect of neuromuscular blockade and reversal by sugammadex versus neostigmine on breathing when hypoxic or hypercapnic in volunteers
- ACRONYMBREATH
- hypothesisA. Rocuronium will induce impairment of carotid body function through blockade of cholinergic neurotransmission in carotid bodies resulting in a reduced or absent ventilatory response to isocapnic hypoxia.
B. Sugammadex will completely restore carotid body function following rocuronium administration with full reversal of the ventilatory response to isocpanic hypoxia within 2 min.
C. Neostigmine will cause a protracted reversal of the carotid body function following rocuronium administration with full reversal within 40-60 min.
- Healt Condition(s) or Problem(s) studiedNeuromuscular blockade, Carotid bodies
- Inclusion criteriaHealthy male volunteers aged 18 and older with a body mass index < 30 kg/m2.
- Exclusion criteriaKnown or suspected neuromuscular disorders impairing neuromuscular function; allergies to muscle relaxants, anesthetics or narcotics; a (family) history of malignant hyperthermia or any other muscle disease; any medical, neurological or psychiatric illness (including a history of anxiety).

- Interventions- Partial neuromuscular block with rocuronium
- Hypoxic and hypercapnic ventilatoy respons
- Antagonizing neuromuscular block with either neostigmine or sugammadex or placebo
- Primary outcome- The effect of partial neuromuscular blockade (NMB; TOF ratio 0.8 and 0.6) induced by low-dose rocuronium on the ventilatory response to isocapnic hypoxia and the effect over time (from TOF 0.6 to TOF 1.0) of the reversal by sugammadex, neostigmine or placebo in healthy volunteers
- Secondary outcomeTo assess the effect of partial NMB (TOF ratio 0.6) induced by low-dose rocuronium on the ventilatory response to hypercapnia and effect over time (from TOF 0.6 to TOF 1.0) of the reversal by sugammadex, neostigmine or placebo in healthy volunteers.
- TimepointsBaseline ventilation, ventilatory measurements every 5 min.

- Brief summaryThis is a randomized, double blind, 3-arm, placebo controlled parallel study on the influence of reversal of a partial NMB on carotid body function following rocuronium administration. Healthy volunteers will be randomized to receive either placebo (Group1, n = 12), neostigmine (1 mg. n =12) or sugammadex (2 mg/kg, n = 12) following a continuous rocuronium infusion for 120 min aimed at a TOF ratio of 0.8 for 1 h followed by 0.6 for another hour. Prior to the rocuronium infusion and during the infusion, ventilatory responses to isocapnic 2-min hypoxic pulses will be obtained as well as the (hyperoxic) ventilatory response to hypercapnia. After the 120 min infusion and the administration of reversal agents, the ventilatory response to hypoxic pulses will be obtained at 5 min interval for at least 60 min. In case the response has not returned to pretreatment control values, additional responses will be obtained. Hereafter, a final ventilatory response to carbon dioxide will be obtained (at hyperoxic conditions).
