ABSTRACT
To evaluate the value of oxycodone hydrochloride for postoperative pain management in patients undergoing patient-controlled intravenous analgesia(PCIA). The medical records on postoperative pain management in our department from January 1 to June 30,2018,were retrospectively analyzed.Totally 136 patients were assigned into oxycodone,sufentanil,or morphine groups according to the opioid used in the PCIA.Patients were assessed for postoperative pain severity(scored with NRS)and adverse reactions 24,36,and 48 hours after surgery.The area under curve(AUC)was calculated. The score of pain at exercise was significantly lower in the oxycodone group(2.2±2.4)than in the sufentanil group(3.4±2.1)(=0.305,=0.0126)or the morphine group(3.4±1.7)(=0.104,=0.0277)36 hours after surgery.AUC at rest was significantly lower in the oxycodone and morphine groups than in the sufentanil group(29.00,27.00,and 40.01,respectively);in contrast,AUC at exercise was significantly lower in the oxycodone group(63.17)than in the sufentanil and morphine groups(82.00 and 80.93,respectively).The consumption of opioids was significantly higher in the sufentanil group[(37.2±16.1),(46.1±24.3),(64.4±33.4)mg]than in the oxycodone group[(20.4±14.8)(=3.571,=0.001),(24.2±16.1)(=4.63,<0.0001),(34.4±25.1)mg(=6.409,<0.0001)]or the morphine group[(16.6±11.7)(=4.233,<0.0001),(20.5±14.1)(=5.250,<0.0001),(28.8±19.0)mg(=7.354,<0.0001)]24,36,48 hours after surgery.The oxycodone group experienced less vomiting(=11.360,=0.003)and early termination of PCIA(=7.914,=0.019)compared with the other two groups. Oxycodone can be used for postoperative PCIA.It can alleviate a variety of postoperative pain,with superior analgesic efficiency and safety to sufentanil and morphine.
ABSTRACT
OBJECTIVE：To investigate the effects of parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with patient controlled intravenous analgesia （PICA） on postoperative analgesia in patients undergoing gynecological laparoscopic surgery and its effect on serum related factors. METHODS ：A total of 280 patients who underwent gynecologic laparoscopic surgery in the Second Affiliated Hospital of Hainan Medical University from Mar. 2017 to Mar. 2019 were randomly divided into control group （group C ），parecoxib sodium group （group P ），and flurbiprofen axetil group （group F ）and lornoxicam group （group L ）acording to random number table ，with 70 patients in each group. Four groups of patients received Sodium chloride injection 5 mL，Parecoxib sodium for injection 40 mg，Flurbiprofen axetil injection 50 mg and Lornoxicam for injection 8 mg （added 8 mg when the effect was not good ）intravenously at 30 min before the end of surgery. At the end of surgery ，they were given PICA of Sufentanil citrate injection and Dizosin injection for analgesia. The situation of pain and nausea symptom were evaluated at 6，12，24 and 48 h after surgery by using numerical rating scale （NRS）. The levels of serum CRP ，IL-6，SP and PGE 2 were detected by chemiluminescence method and ELISA. The times of pressing PICA pump and the dosage of analgesic were recorded in 4 groups within 24 h after surgery. The ADRs of patients within 48 h after surgery were recorded ，such as bloating ， dizziness，itchy skin ，respiratory depression and urinary retention. RESULTS ：At different time points ，the NRS scores of pain of group P ，F and L were significantly lower than those of group C ；and 48 h after surgery ，NRS score of pain of group L was significantly lower than those of group P and F （P＜0.05）. There was no statistical significance in the level of CRP ，IL-6，SP and PGE2 of 4 groups before surger （P＞0.05）. The CRP ，IL-6，SP and PGE 2 levels at each time point after surgery of group P ，F and L were significantly lower than those of group C ；compared with group P ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12，24 and 48 h after surgery were significantly decreased in group F ，and serum level of IL- 6 at 48 h after surgery，serum levels of SP at 24 and 48 h after surgery ，serum levels of PGE 2 at 12，24，48 h after surgery were decreased significantly in group L ；compared with group F ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12， 24，48 h after surgery were all decreased significantly in group L （P＜0.05）. There was no statistical significance in the incidence of anausea and vomiting among 4 groups（P＞0.05）. CONCLUSIONS ：Parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with PICA can effectively relieve the pain of patients after gynecological laparoscopic surgery and reduce the levels of serum related factor ，and lornoxicam has the most obvious effect.

ABSTRACT
Objective To investigate the effects of dexmedetomidine combined with butorphanol on postoperative an-algesia and recovery for patient-controlled intravenous analgesia (PCIA) in parturients undergoing cesarean section. Methods Eighty-four parturients scheduled for elective caesarean section under spinal anaesthesia were randomly al-located into two groups. Control group: physiological saline infusion(0.5 μg/kg) after delivery and butorphanol (10 mg) in PCIA. Experimental group: dexmedetomidine (0.5 μg/kg) infusion after delivery and dexmedeto-midine (200 μg) with butorphanol (10 mg) in PCIA. Hemodynamic variables, the visual analogue score (VAS), the sedation score, side effects, the total pump-press number and additional analgesics cases were re-corded. The quality of recovery was evaluated by using a 40-item quality of recovery questionnaire(QoR-40) and a 9 questions fatigue score(FFS). Results Compared with control group,the VAS scores,the total pump-press number, the incidence of side effects and the FSS scores in experimental group was significantly decreased (P<0.05). In addition,the QoR-40 score at POD3 was significantly increased(P<0.05). Conclusions Dexmedeto-midine combined with butorphanol for PCIA after caesarean section decreases the consumption of butorphanol,pro-motes postoperative analgesia,alleviates fatigue,and improves postoperative recovery.

ABSTRACT
OBJECTIVE:To compare the effects of dezocine and nalbuphine on patient-controlled intravenous analgesia(PCIA) in patients undergoing cesarean section. METHODS:A total of 97 patients undergoing selective cesarean section were selected from our hospital during Jun. 2015 to Mar. 2017. They were divided into dezocine group(52 cases)and nalbuphine group(45 cases) according to lottery. Both groups received cesarean section under combined spinal-epidural anesthesia,and then given PCIA pump immediately after surgery. The pump of dezocine group was Dezocine injection 0.5 mg/kg+Tropisetron hydrochloride injection 10 mg;that of nalbuphine group was Nalbuphine hydrochloride injection 2 mg/kg+Tropisetron hydrochloride injection 10 mg. Both groups of analgesic drugs were diluted 100 mL with 0.9% sodium chloride injection,constant infusion of liquid medicine at rate of 2 mL/h,adding 0.5 mL additionally each time,for consecutive 48 h. VAS score and Ramsay sedation score of resting pain, dynamic pain and uterine contraction pain were performed in 2 groups 4,8,12,24,48 h after surgery. The serum levels of PRL were determined 30 min before surgery and 24,48 h after surgery. The initial time of lactation and ADR were recorded in 2 groups. RESULTS:VAS score of resting pain and uterine contraction pain at 4,8,12 h after operation and that of dynamic pain at 4,8,12, 24 h after operation were significantly lower in dezocine group than nalbuphine group,with statistical significance (P＜0.05). There was no statistical significance in VAS score between 2 groups at other time points(P＞0.05). As time went on,the VAS scores of the two groups decreased significantly at each time point,and the difference was statistically significant(P＜0.05). The serum levels of PRL in 2 groups 24 and 48 h after operation were significantly higher than 30 min before operation,with statistical significance(P＜0.05). There was no statistical significance in serum level of PRL between 2 groups at same time point(P＞0.05). There was no statistical significance in Ramsay score, initial time of lactation or the incidence of ADR between dezocine group and nalbuphine group (P＞0.05). CONCLUSIONS:Both dezocine and nalbuphine are effective analgesia drugs of PCIA in patients undergoing cesarean section. Early postoperative analgesic effect of dezocine is superior to nalbuphine. They have similar effects on long-term analgesia and postoperative sedative,serum level of PRL,initial time of lactation,as well as safety.
ABSTRACT
Objective To compare the effectiveness of patient-controlled intravenous analgesia with or without background infusion of dezocine plus flurbiprofen axetil injection in patients undergoing laparoscopic colorectal cancer operation. Methods Sixty patients scheduled for laparoscopic colorectal cancer surgery,35 males and 25 females,aged 18-65 years,ASA physical status Ⅰ or Ⅱ,were randomly divided into 2 groups:common-dose background infusion group(Group CB,n = 30),and no background infusion group(Group NB, n = 30). All patients were intravenously administered a PCA pump containing dezocine 0.6 mg/kg,flurbiprofen axetil 3 mg/kg and normal saline in a volume of 120 mL.Patients in Group CB were given background infusion rate of 2 mL/h with PCA bolus dose 2 mL,patients in Group NB were given PCA bolus dose 4 mL only.NRS scores, Ramsay sedation scores,pressing times,consumption of analgesic,supplementary analgesics,incidence of ad-verse reactions,time of first exhaust,time of first leaving bed and patients'satisfaction scores were recorded after surgery. The influence factors of time of first exhaust and time of first leaving bed were also analyzed. Results Compared with group CB,the NRS scores in group NB were higher both at rest and during movement(P<0.05), the Ramsay sedation scores in group NB were lower at 24 and 48 h after surgery(P<0.05),the pressing times in group NB were higher(P < 0.05),the consumption of analgesic in group NB were lower after surgery,and the incidence of using supplementary analgesics was higher(P < 0.05). No statistical difference was found on the in-cidence of adverse reactions between the two groups(P > 0.05). Moreover,the time of first leaving bed in group NB was longer than that in group CB(P<0.05).The satisfaction scores in group NB was lower than that in group CB(P<0.05).The main influence factors of the time of first leaving bed were gender and NRS score during move-ment at 24 h after the operation(P<0.05).The main influence factors of the time of first exhaust were age,BMI and fluid infusion volume(P < 0.05). Conclusion Postoperative patient-controlled intravenous analgesia with background infusion of dezocine and flurbiprofen axetil injection was more efficacious and satisfactory,and more suitable in postoperative pain management.

Objective To study the effect of sufentanil combined with nalbuphine on patient-controlled intravenous analgesia (PCIA)management after cesarean section.Methods The obj ects of study included 150 primiparas who underwent cesarean section in our hospital from January 2016 to March 2017,aged 20-35 years,weighing 54-89 kg,ASA physical status Ⅰ or Ⅱ.The primiparas were randomly divided into three groups,50 in each group.Sufentanil group (group S):sufentanil 2 μg/kg+tropisetron 10 mg;Nalbuphine group (group N):nalbuphine 2 mg/kg+tropisetron 10 mg;Sufentanil combined with nalbuphine group (group SN):sufentanil 1 μg/kg+nalbuphine 1 mg/kg+tropisetron 10 mg.The VAS scores,Ramsay scores and the incidence of respiratory depression of pain (rest,coughing)and Ramsay sedation scores were observed at 1,3,6,9,12,24,36 h after the caesarean section.Actual pressing times of PCIA were further evaluated.Adverse reactions were ob-served,such as nausea and vomiting,respiratory depression.Results There was no statistical differ-ence in VAS scores,Ramsay scores and the incidence of respiratory depression of patients at rest a-mong the three groups.However,when coughing,the VAS scores in patients of group SN were sig-nificantly lower than those of groups S and N (P<0.05).The incidence of nausea and vomiting in group N and group SN was significantly lower than that in group S (P<0.05).The actual pressing times of PCIA were significantly less in group SN than those in group S and group N (P<0.05). Conclusion Sufentanil combined with nalbuphine can achieve satisfactory analgesic effect on PCIA management after cesarean section.
ABSTRACT
Objective To observe the effect of patient controlled intravenous analgesia(PCIA)of remifentanil combined with butorphanol in high-intensity focused ultrasound(HIFU)treatment of uterine fibroids or adenomyosis. Methods A total of 56 patients with uterine fibroids or adenomyosis treated with HIFU were selected.At 15 min before the treatment,1 mg of butorphanol was intravenously injected,and then a PCIA pump was connected.The PCIA solution was butorphanol 2 mg and remifentanil 2 mg diluted to 100 ml.The initial dose was 1 μg/kg,the basal rate was 6 μg· kg-1· h-1,the bolus was 1 μg/kg,and the lock out time was 1 min.The respiratory rate,heart rate,mean arterial pressure(MAP),oxygen saturation(SpO2), VAS scores,and Ramsay sedation scores were recorded at each time points,which were T1(at the beginning of surgery),T2(the vital signs were recorded every 30 min during the surgery,the mean values of the data were taken as T 2 values),T3(the end of surgery),and T4(30 min after the end of surgery).Additional medications and complications,such as dizziness,nausea,vomiting,respiratory depression were recorded,too. Results The operations were accomplished in all the 56 cases.The operation time was(97.8 ±44.7)min.As compared to the T1 time point,the MAP and SpO2during and after treatment at each time points had no significant differences(F=1.398, P=0.245;F=1.819, P =0.155).The respiratory frequency and heart rate during treatment significantly decreased as compared to before treatment(F=109.020,P=0.000;F=115.023,P=0.000).At 30 min after treatment,the respiratory frequency rose but had no significant difference as compared to the baseline(P=1.000).The heart rate also speeded up but still below the level at the beginning of the treatment,with the difference having statistical significance(P=0.002).Analgesia effective rate was 94.6%(53/56).The Ramsey scores were(2.4 ±0.5)points during the treatment,(2.2 ±0.5)points at the end of the treatment,and(2.0 ±0.2)points at 30 min after treatment.The sedation effect was satisfactory. Conclusion PCIA of butorphanol combined with remifentanil is effective and safe for HIFU in the treatment of uterine myoma or adenomyosis.

CONCLUSION: The PCIA regimen of tramadol group is superior to that of the hydromorphone group, considering the efficacy, safety and economy.
ABSTRACT
Objective • To investigate the effects of dexmedetomidine combined with sufentanil in patient-controlled intravenous analgesia (PCIA) of puerperae with severe preeclampsia after cesarean section. Methods • A total of 250 puerperae with severe preeclampsia who prepared to be treated by cesarean section were divided into observation group and control group by the random number table method with 125 cases in each group. They were given PCIA after operation. The PCIA formula for the observation group was dexmedetomidine combined sufentanil while that for the control group was sufentanil alone. The heart rate (HR) and mean arterial pressure (MAP) were compared between the two groups at different time points. Scores of visual analogue scale (VAS) and Ramsay sedation scale (RSS), the dosage of sufentanil and adverse drug reactions in both groups were recorded at 4, 8 and 24 hours after operation. Results • The HR and MAP of the observation group were significantly lower than those of the control group at 4, 8 and 24 hours after operation (all P<0.05). VAS scores in the observation group were significantly lower than those in the control group while RSS scores were significantly higher than those in the control group. The dosage of sufentanil was significantly less than that in the control group at 4, 8 and 24 hours after operation (all P<0.05). The incidence rates of nausea and vomiting in the observation group (12.80% and 7.20%) were significantly lower than those in the control group (32.00% and 16.00%) (all P<0.05). Conclusion • Compared with sufentanil alone, dexmedetomidine combined with sufentanil not only can significantly enhance the analgesic and sedative effects, but also can significantly reduce the dosage of sufentanil, and reduce adverse drug reactions in PCIA of puerperae with severe preeclampsia after cesarean section.
ABSTRACT
Propósito: Describir la periodicidad del momento de máxima intensidad del dolor de las contracciones uterinas (CUs) durante el trabajo de parto (TDP) para eventualmente permitir el desarrollo de nuevos modelos de administración de analgesia endovenosa. Material y método: Embarazadas de término en TDP, reclutadas desde marzo 2014 por 18 meses, de manera no probabilística consecutiva. Se obtuvo el momento de máximo dolor por autoreporte de las pacientes con cronómetros, previa capacitación. Análisis: Regresión para medidas repetidas de efectos mixtos a los 3-5, 6-7 y 8-10cm de dilatación. La variable respuesta es el intervalo de tiempo desde el momento de máximo dolor de la CU basal al de la contracción siguiente. Resultados: En 64 pacientes, se obtuvo 5 intervalos de tiempo. Para la dilatación de 3-5cm una mediana=140.92 segundos y los coeficientes de regresión (CR) en 4 intervalos de tiempo con respecto al basal de 4.2, 15.9, -2.7 y -5.8 segundos. Para 67cm una mediana=131.16 seg y CR 13.4, 11.3, 2 y -10 seg. Para 8-10cm una mediana=129.3 seg y CR -6.7, 0.49, -2.5 y -7.7 seg. No hubo diferencias significativas entre los coeficientes de regresión. Conclusiones: Con los datos obtenidos podemos señalar que no hubo diferencias estadísticas significativas entre los intervalos de tiempo de los momentos de máximo dolor durante el TDP en fase activa. Esta información es relevante para apoyar el desarrollo de un modelo predictivo del dolor.
Aim: To describe the timing of the moment of maximum intensity of uterine contraction (UC) pain in labor to possibly enable the development of new models for administering endovenous analgesia. Materials and Methods: Full-term pregnant women in labor, recruited from March 2014 for 18 months, using consecutive nonprobability sampling. The moment of maximum pain was ascertained as self-reported by patients previously trained with chronometers. Analysis: Regression for repeated measurements from mixed results at 3-5, 6-7 and 8-10cm of dilation. The response variable was the time interval from the moment of maximum pain of the baseline UC to the following contraction. Results: In 64 patients, 5 time intervals were obtained. For the dilation of 3-5cm, a median=140.92 seconds and regression coefficients (RC) in 4 time intervals relative to the baseline of 4.2, 15.9, -2.7 and -5.8 seconds. For 6-7cm, a median =131.16 sec and RC 13.4, 11.3, 2 and -10 sec. For 8-10cm, a median =129.3 sec and RC -6.7, 0.49, -2.5 and -7.7 sec. There were no significant differences among the regression coefficients. Conclusions: With the data collected we can report that there were no statistically significant differences between the time intervals of the moments of maximum pain during active labor. This information is relevant to support the development of a predictive model for this pain.

Methods Forty patients (20 males and 20 females,ASA physical status Ⅰ or Ⅱ),scheduled for e-lective video-assisted thoracoscopic lobectomy,were randomly assigned into two groups,ESP block combined with PCIA group (group EP)and PCIA only group (group P).ESP block was given to pa-tients in group EP before operation,and its effect was evaluated by testing the area of block.VAS scores were recorded at 1,6,18,24 and 48 h after operation.The frequency for compress PCIA,the volume of analgesic drugs,the consumption of flurbiprofen axetil and the side-effects were recorded as well.Results ESP block was accomplished in group EP with sensory loss from T2-T8 or T3-T7 over the entire posterolateral aspect of the hemithorax.And there were no puncture-related complications. The VAS scores both at rest and coughing in group EP were lower than those in group P (P <0.05). The compress PCA numbers,the volume of analgesic drugs and the consumption of flurbiprofen axetil were significantly less in group EP than those in group P (P <0.05).Only nausea and vomiting were observed as postoperative side effects,and there were no significant differences between the two groups.Conclusion Ultrasound-guided single erector spinae plane block combined with PCIA is a sa-fer and more effective method for the analgesia of thoracic operation than PCIA only.
ABSTRACT
Objective To investigate the clinical effect of different patient-controlled analgesia (PCA) modes in patients undergoing laparoscopic hysteromyomectomy.Methods Sixty patients scheduled for a laparoscopic hysteromyomectomy were randomly divided into three groups.All patients received an intravenous infusion of parecoxib sodium (40 mg) as preventive analgesia 15 min prior to the skin incision.Thirty minutes prior to the end of surgery,they received an intravenous injection of sufentanil (0.1 μg/kg) as a loading dose.The following data were collccted:the total dosage of sufentanil,the total and valid frequency of the PCA press,visual analog pain score,sedation score,the incidence of adverse reactions,the incidence of adverse reactions per group.Results Compared to groups 1 and 2,group 0 had the lowest dosage of sufentanil.There was no significant difference in the incidence of adverse reactions between the three groups (P ＞0.05).Conclusion The PCA-only mode,in conjunction with parecoxib sodium as preventive analgesia,was more suitable for patients undergoing laparoscopic hysteromyomectomy.
ABSTRACT
Objective To study the clinical effect of remifentanil intravenous patient-controlled analgesia pump combined with psychological intervention in labor analgesia.Methods 100 cases of maternal in our hospital from April 2015 to July 2016 were selected as the research object in this study.They were randomly divided into the control group and the experimental group, each group had a total of 50 cases.Patients in the control group were treated with intravenous patient-controlled analgesia pump, while the experimental group received psychological intervention on the basis of remifentanil treatment.The anxiety, pain and cesarean section were compared between the experimental group and the control group.Results After the corresponding treatment, the experimental group of 50 patients, the number of cases of cesarean section in 6 cases, the rate of cesarean section was 12%, in the control group of patients with a total of 50 cases, the number of cases of cesarean section in patients with cesarean section rate of 28%.But the control group was significantly higher than that of the experimental group, the difference was statistically significant(P<0.05).The visual analogue score of the experimental group was significantly lower than that of the control group, with statistical difference(P<0.05).The incidence of adverse reactions in the experimental group was 18%, and the incidence of adverse reactions in the control group was 14%.The number of patients with moderate anxiety in the control group was significantly higher than that in the experimental group, with statistical difference(P<0.05).Conclusion Remifentanil intravenous analgesia pump combined with psychological intervention for clinical effect of labor analgesia is better, can effectively eliminate the anxiety of patients, relieve pain, and high safety, is further applied in clinical significance.
ABSTRACT
OBJECTIVE:To investigate the effects of preemptive analgesia of parecoxib-sodium for radical mastectomy of breast cancer. METHODS:A total of 60 female patients underwent selective radical mastectomy of breast cancer under general anes-thesia were randomly divided into observation group(40 cases)and control group(20 cases). 15 min before anesthesia induction, observation group was given intravenous injection of Parecoxib-sodium for injection 40 mg. Control group was given intravenous in-jection of 0.9% Sodium chloride injection 5 mL. The pain visual analogue scale(VAS),the frequency of patient controlled intrave-nous analgesia(PCA)and ADR were observed between 2 groups at different time points after surgery. RESULTS:VAS scores of observation group were significantly lower than those of control group 2,4,6,8 h after operation,and the frequency of PCA 0-4, 4-12,12-24,24-36 h after operation was significantly lower than control group,with statistical significance(P0.05). CONCLUSIONS:The preemptive analgesia of parecoxib-sodium can effectively reduce pain degree of patients with breast cancer after radical mastectomy,the frequency of PCA, and do not increase the occurrence of ADR.
