ABSTRACT
Objective To study curative efficacy of dezocine in treatment of receiving laparoscopic appendectomy and its effects on white blood cell count and c reactive protein.Methods 90 patients of laparoscopic appendectomy who received therapy from January 2015 to October 2016 in our hospital were selected as research objects,according to random number table,those patients were divided into the observation group and the control group,45 cases in each group.The control group was treated with sufentanil, while the observation group was treated with dezocine.Then operation index, T0 (preoperative),T1(extubation),T2(after extubation) mean arterial pressure(MAP),heart rate(HR), respiration rate(RR),isual analogue scale/score ( VAS) , ramsay score ( RSS) , white blood cell count and c reactive protein of two groups after treatment were compared .Results After treatment, MAP,HR in the observation group were significantly lower than control group [(78.30 ±6.20)mmHg vs.(86.08 ±6.09)mmHg,(76.45 ±5.90)mmHg vs.(80.48 ±5.80)mmHg,(90.82 ±9.50)time/min vs.(96.73 ±9.83)time /min,(87.21 ±8.15)time /min vs.(93.59 ±9.90)time /min](P<0.05); VAS, RSS score were significantly lower than the control group[(2.60 ±0.70)score vs.(5.29 ±0.83)score,(3.53 ±0.92)score vs.(6.38 ± 1.21)score](P<0.05); White blood cell count, c reactive protein were significantly lower than the control group[(7.92 ±2.01) ×109/L vs.(14.98 ±2.11) ×109/L,(7.90 ±2.30)mg/L vs(12.46 ±3.10)mg/L](P<0.05).Conclusion Dezocine is well for receiving laparoscopic appendectomy, obvious analgesic effect, can significantly reduce the white blood cell count and c reactive protein.
ABSTRACT
Objective To investigate the efficacy of dexmedetomidine-assisted topical anesthesia in patients undergoing bronchoalveolar lavage ( BAL). Methods Twenty-four ASA Ⅱ or Ⅲ patients in ICU, aged 24-64 yr, weighing 50-80 kg, scheduled for BAL, were randomly divided into 2 groups ( n = 12 each) : topical anesthesia group (group A) , topical anesthesia + dexmedetomidine group (group B) . In group A, 0.9% normal saline 5 ml was injected intravenously 30 min before operation, 2% lidocaine 5-10 ml was given via a tracheal tube or cannula 5 min before operation and then an increment of 2% lidocaine 5 ml was given using fibreoptic bronchoscope every 15-30 min as required (the total amount was within 20 ml) . In group B, dexmedetomidine 0.5-1.0 μg/kg was injected (time of injection≥ 10 min) followed by infusion at 0.1-0.5 μg·kg-1 ·h-1 and the topical anesthesia was performed as the method described in group A. The time of lavage, adverse reactions and adverse cardiovascular events were recorded. Blood samples were taken 20 min before lavage, 20 min after the start of lavage and 20 min after the end of lavage (T1-3 ) for determination of the concentrations of plasma catecholamine and serum cortisol. Results The incidences of adverse reactions and adverse cardiovascular events were significantly lower and the operation time was significantly shorter in group B than in group A ( P < 0.05). The concentrations of plasma catecholamine and serum cortisol were significantly higher at T2，3 in group A, while lower at T2，3 in group B than at T1 ( P < 0.05) . The concentrations of plasma catecholamine and serum cortisol were significantly lower in group B than in group A ( P < 0.05). Conclusion Dexmedetomidine-assisted topical anesthesia can be used safely and effectively in BAL.
