Objective:To study the therapeutic effects of pressure controlled ventilation on posttraumatic acute respiratory distress syndrome(ARDS).Methods:Eighteen patients with posttraumatic ARDS were included in the study.The patients received mechanical ventilation immediately after admission and were randomly divided into two groups:pressure controlled ventilation (PCV) group (n=8) and volume controlled ventilation (VCV) group (n=10).Peak airway pressure (PIP),mean airway pressure (MPaw) and positive endexpiratory pressure(PEEP) at 6 hour (PTh6) and 12 hour (PTh12) after treatment in the two groups were recorded and compared.Blood gas analysis,blood pressure,heart and respiratory rates were compared before and after PCV treatment.Results:PIP in PCV group at PTh6 and PTh12 were (2 24±0 12)kPa (1 kPa=10 20 cmH 2O) and (1 98±0 08)kPa,respectively,and were significantly lower than those in the VCV group (both P<0 01).The MPaw and PEEP in PCV group at PTh6 were (1 12 ±0 09)kPa and (0 79±0 12)kPa,respectively,and showed no significant difference with those in the VCV group (both P>0 05).But the two parameters at PTh12 in PCV group,which were (0 85±0 08) kPa and (0 55±0 04) kPa respectively,were significantly lower than those in the VCV group (P0 05 and P<0 01).The blood gas analysis,heart and respiratory rates were obviously improved in PCV treatment group,and no significant changes in blood pressure was observed.Conclusions:PCV can significantly lower the PIP level with no disturbance to MPaw,PEEP and hemodynamics.It is useful in the treatment of posttraumatic ARDS.

Objective To observe the effect of inverse ratio ventilation (IRV) on hemodynamics and oxygen metabolism in sheep with acute respiratory distress syndrome (ARDS). Methods Twelve ARDS sheep induced by LPS were admitted to this study,and received mechanical ventilation with volume controlled (VC) and pressure controlled ventilation (PC) (conventional ratio and inverse ratio) at the same level of total positive end expiratory pressure (PEEPt),data of hemodynamics and oxygen metabolism were collected at 30 min after the onset of each mode. Results With PC,peak airway pressure was lower than that with VC,but mean airway pressure was higher with IRV. At the same level of PEEPt,there was no difference in hemodynamics and oxygen metabolism between VC and VC IRV,same as PC and PC IRV But compared with VC,arterial oxygen pressure and arterial oxygen saturation with PC IRV were lower significantly ( P <0 05). Conclusion PEEPt was a very important factor to improve oxygenation,short term IRV was not better than VC or PC

Objective To investigate the effects of different modes of mechanical ventilation on lung function during open heart surgery in children with pulmonary hypertension (PH). Methods Twenty-four patients with moderate PH aged 3 mon-12 yr 2mon (group M) and twenty-four patients with severe PH aged 3 mon-7yr 9mon (group S) were further divided randomly into 3 subgroups based on the modes of mechanical ventilation used: pressure-controlled ventilation(PCV) only and alveolar pressure (Palveo) was maintained at 0 cm H2O during CPB (group M1/S1 n = 8); PCV + PEEP (2 cm H2O) and Palveo was maintained at 2 cm H2O during CPB (group M2/S2 n = 8); and PCV+ PEEP (4 cm H2O) and Palveo was maintained at 4 cm H2O during CPB (group M3/S3 n=8). The patients were premedicated with atropine 0.01 mg ·kg -1 and midazolam 0. 1 mg·kg-1 . Anesthesia was induced with fentanyl 20μg·kg-1 and vecuronium 0. 1 mg·kg-1 and maintained with vecuronium infusion(70μg·kg-1·h-1 ) and inhalation of N2O-O2 and isoflurane. The children were mechanically ventilated after intubation and the ventilatory parameters were VT = 10-12 ml ?kg-1, F = 20 bpm and I : E = 1: 2. Lungs were lavaged and 2-3 ml of aspirate were taken for determination of surfactant. Total protein (TP), total phospholipid -(TPL), saturated phosphatidylcholine (Sat PC) and respiratory system compliance(Crs) was measured before skin incision( T0 ), before CPB (T,), at the end of CPB ( T2) and at the end of surgery(T3 ) . Results (1) Crs decreased significantly at T2 and T3 as compared with that at T0 and T1 in group M1/S1 and M2/S2 but in group M3/S3 there was no significant difference in Crs between T0, T1 and T2-3. (2) Sat PC/TPL and Sat PC/TP decreased significantly after CPB (T2, T3 ) in group M,/S, and M2/S2 but in group M3/S3 there was no significant difference in Sat PC/TP and Sat PC/TPL between T0-1 and T2-3. Conclusion PEEP 4 cm H2O can effectively prevent postoperative lung function from worsening in children with pulmonary hypertension undergoing open heart surgery with CPB.
