[Anesthetic and respiratory care for patients undergoing magnetic resonance imaging].
Simple and small ventilators, paraPAC and ventiPAC (pneuPAC) were used for anesthetic and respiratory care of patients undergoing magnetic resonance imaging (MRI), combined with or without MRI-compatible anesthetic machine, Ohmeda (R) Excell 210. These ventilators can be connected to Excell by the addition of a conventional below for ventilator (Ohmeda). The 1.5 tesla room shield type MRI machine (SIGNA, GE) did not interfere with the functions of the ventilator and anesthetic machine placed near the patient. Oscillometric blood pressure monitor (BP-203, Nippon Colin) and a gas and pulse oximetry (RGM, Ohmeda) monitor were used with 6 m extended lines for monitoring in the next room. Pulse oximetry signals were disturbed sometimes only by radiofrequency pulses for 3 to 10 minutes, but a pulse oximeter was one of the most useful monitors. Two representative cases were reported here. These ventilators can be used for almost all MRI cases with or without MRI compatible anesthetic machines.
