Outcome Measures

Primary Outcomes (2)

  • Measure of pain intensity according to the Numeric Pain Rating Scale (NPRS) 2-3 minutes after drug administration in relation to pain intensity assessed before drug administration

    NPRS score before and 2-3 minutes after drug administration in each study arm

    2-3 mins

  • Measure of pain intensity according to the Numeric Pain Rating Scale (NPRS) immediately after PCI in relation to pain intensity assessed before drug administration

    NPRS score before drug administration and and immediately after PCI in each study arm

    immediately after PCI

Secondary Outcomes (5)

  • Adverse effects of evaluated therapies

    24 hours

  • Need for GPIIb/IIIa (glycoprotein IIb/IIIa) inhibitor administration during PCI due to large intracoronary thrombus

    24 hours

  • Angiographic effect of PCI using Thrombolysis In Myocardial Infarction (TIMI) scale

    through study completion, an average of 1 year

  • Angiographic effect of PCI using TIMI Myocardial Perfusion Grade (TMPG) scale

    through study completion, an average of 1 year

  • ST elevation resolution in STEMI patients after PCI

    1 hour after PCI

Study Arms (2)

EXPERIMENTAL

Patients treated with inhaled methoxyflurane (3 mg)

Drug: Methoxyflurane - Penthrox

Morphine

ACTIVE COMPARATOR

Patients treated with intravenous morphine (5 mg)

Drug: Morphine

Interventions
