ABSTRACT
ObjectiveTo observe the changes of the respiratory dynamics during expand thymectomy,and to explore the protection of ulinastatin on pulmonary function.MethodsSixty patients with myasthenia gravis( Ossermann Ⅰ,Ⅱ b)undergoing expand thymectomy were randomly divided into control group( group C,n =30)and ulinastatin group( group U,n =30).Patients in ulinastatin group received intravenous injection of ulinastatin 4000 U/kg in 20 ml physiological saline immediately after entering operating room and pumped ulinastatin 2000 U/( kg · h)to the end of the operation continuously.Patients in control group received the same volume of normal saline.Heart rate ( HR ),mean arterial pressure ( MAP ),lung compliance,airway peak pressure,plateau airway pressure,inspiratory and expiratory resistance were monitored before induction of anesthesia( T1 ),during skin incision ( T2),at 30 min after operation ( T3 ) and at 60 min after operation (T4),at the end of operation before extubation(T5).ResultsCompared with T1,HR and MAP at T2 in two groups were increased obviously [ group U HR( 90.2 ± 13.5 ) bpm vs ( 78.6 ± 10.4 ) bpm,MAP( 15.5 ± 2.3 ) kPa vs ( 12.1 ± 1.5)kPa;group C HR(94.3 ± 15.4)bpm vs(81.6 ± 12.2)bpm,MAP( 16.8 ± 2.6) kPa vs( 12.6 ±1.8)kPa,P < 0.05 )].There was no significant difference on HR,MAP at each time between the two groups (P >0.05).At T3,T4,T5,the lung compliance was significantly decreased when compared with T1 [ group UT3,T4,TS(51.23 ± 12.33) ml/cm H2O,(50.35 ± 13.29) ml/cm H2O and(50.65 ± 13.16) ml/cm H2O vs T1 (53.69 ± 14.34) ml/cm H2O;group CT3,T4,T5(41.56 ± 11.20)ml/cm H2O,(42.02 ± 10.12) ml/cm H2O and(39.85 ± 10.31 ) ml/cm H2O vs T1 ( 53.45 ± 15.21 ) ml/cm H2O; P < 0.05 ) ].Airway peak pressure,plateau airway pressure,inspiratory and expiratory resistance at T3,T4,T5 were obviously increased compared with T1 in two groups [ airway peak pressuregroup U( 13.04 ± 2.14 ) cm H2O,( 13.12 ± 2.42 ) cm H2O,(13.22±2.48)cm H2O,vs(12.04 ±2.12)cm H2O;group C(16.25 ±3.27)cm H2O,(15.56 ±4.34)cm H2 O,( 16.64 ± 3.45 ) cm H2O,vs ( 13.12 ± 2.32 ) cm H2O; plateau airway pressuregroup U( 10.54 ±2.46) cm H2O,( 11.76 ± 3.11 ) cm H2O,( 12.02 ± 3.25 ) cm H2 O,vs ( 9.48 ± 2.13 ) cm H2O; group C(15.02 ±3.87)cm H2O,( 15.51 ± 3.13) cm H2O,( 15.67 ± 3.02) cm H2O,vs (9.25 ± 1.26) cm H2O;inspiratory resistancegroup U( 8.56 ± 2.52 ) cm H2O,( 9.31 ± 3.06 ) cm H2O,( 8.44 ± 2.45 ) cm H2O,vs (8.25 ±2.20)cm H2O;group C(11.52 ±3.06)cm H2O,(12.16 ±3.02)cm H2O,(12.83 ±3.14)vs ( 8.31 ± 2.24 ) cm H2O ; expiratory resistancegroup U( 10.22 ± 2.24 ) cm H2O,( 10.34 ± 2.66 ) cm H2O,(10.27 ± 2.22) cm H2O,vs(8.46 ± 2.37) cm H2O; group C(14.43 ±3.18)cm H2O,(14.56 ±3.32)cm H2O,( 14.46 ± 3.52 ) cm H2O,vs ( 8.55 ± 2.18 ) cm H2O; P < 0.05 ) ].The increased degree of lung compliance and the decreased degree of airway peak pressure,plateau airway pressure,inspiratory and expiratory resistance at the time of T3,T4,T5 and T1 in ulinastatin group were all significantly higher than those in control group(F=6.167,3.138,4.137,5.217,4.361,respectively,P <0.05).ConclusionUlinastatin can improve respiratory dynamics,reduce lung injury,and play a protective role in patients with myasthenia gravis.
