ABSTRACT
Objective: To observe the clinical effect of combined spinal epidural anesthesia(CSEA)by using orbital needle in patient-controlled epidural analgesia(PCEA)post cesarean delivery.Methods: 94 puerperas who received cesarean were divided into observation group(47 cases)and control group(47 cases).The patients of two groups were narcotized by using CSEA combined with PCEA.And the observation group adopted a new type of lumbar vertebral combined puncture needle and the control group adopted the traditionally typical lumbar vertebral combined puncture needle.The score of visual analogue scale(VAS)and sedation score of Ramesay of two groups of postoperative 1h,4h,12h,24h and 48h were compared.And the number of times in 48h,the drug dosage and adverse reaction of using analgesia pump also were compared.Results: In postoperative 12 h,the VAS scores of the two groups showed an increasing trend.And the VAS scores of pain of two groups within postoperative 12-48 h decreased gradually.The differences of VAS scores of pain of two groups within postoperative 1-12h and 12-48h between observation group and control group were statistically significant(F=29.596,F=156.366,P＜0.05),respectively.And the VAS scores of pain post operative 4h and 12h of observation group [(2.01±0.51)and(3.49±0.74)]were significantly lower than that of control group [(2.32±0.47)and(3.85±0.69)](t=3.064,t=2.439,P＜0.05),respectively.Within postoperative 1-48h,there were no significant fluctuation in sedation score of Ramesay and the difference of sedation score between the two groups were no significant.And the number of times(11.35±3.04)and drug dosage(65.67± 7.98)mL of using analgesic pump of observation group were significantly lower than that of control group [(20.08±5.32)and(82.07 ± 9.05)mL],(t=9.768,t=9.318,P＜0.05),respectively.Besides,the incidences of postoperative nausea and skin pruritus of observation group(4.26％and 14.89％)were significantly lower than that of control group(17.02％and 34.04％)(x2=4.029,x2=4.663,P＜0.05),respectively.Conclusion: The analgesia effect of orbital needle external needle in implementing CSEA for cesarean delivery is better than that of traditional needle inner needle,and its adverse reactions are less and it is safety.
ABSTRACT
Objective To compare the impact of patient controlled epidural analgesia with patient controlled intravenous analgesia on postoperative recovery and complications in patients undergoing laparotomy pancreatic surgeries.Methods Forty patients undergoing pancreatic surgeries, 27 males and 13 females, aged 18-70 years, ASA physical status Ⅰ or Ⅱ, were randomly divided into two groups (n=20 each).Patients in group E received T8-9 or T9-10 epidural block, 2% lidocaine test dose was given to ensure the location of epidural catheter, after that, each patient in group E was given 0.375% ropivacaine 5 ml into epidural space before skin incising and incision closures.Meanwhile, patients in groups E and V received propofol-sevoflurane combined intravenous inhalation anesthesia.After surgery, patients in group E received patient controlled epidural analgesia while patients in group V received patient controlled vein analgesia.Length of hospital stay, time to ambulation and exhaust defecation were recorded.Other complications were compared.Results Compared to group V, patients in group E showed earlier ambulation [(50.4±4.2) h vs (64.2±5.0) h, P<0.01], shorter hospital stays [(18.5±8.5) d vs (21.5±6.8) d, P<0.05].There was no statistically significant difference in flatus time between the two groups [(39.7±4.1) h vs (39.5±8.4) h].There was no significant difference in complications between the two groups.Conclusion The present study shows that for patients undergoing pancreatic surgeries, patient controlled epidural analgesia could effectively release post-operative pain, shorten the ambulation time and length of hospital stay with no extra complications.
ABSTRACT
OBJECTIVE:To compare the effects of morphine and nalbuphine on related indexes of maternal after cesarean sec-tion. METHODS:A total of 120 maternal underwent cesarean section were randomly divided into observation group(60 cases)and control group (60 cases). After surgery,observation group was given Nalbuphine hydrochloride injection 20 mg+0.75% Ropiva-caine hydrochloride injection 20 mL for patient-controlled epidural analgesia. Control group was given Morphine hydrochloride injec-tion 8 mg+0.75% Ropivacaine hydrochloride injection 20 mL for patient-controlled epidural analgesia. VAS score,systolic pres-sure,diastolic pressure,respiration rate(RR),SpO2 at the onset of analgesia(T0),6 h(T1),12 h(T2),24 h(T3)and 48 h(T4) after analgesia as well as the levels of IL-6,IL-8,CRP and PRL at T0,T3,T4 were observed in 2 groups. The satisfaction rate of analgesia and the occurrence of ADR were also observed. RESULTS:There was no statistical significance in satisfaction rate of an-algesia between 2 groups(96.67% vs. 98.33%,P>0.05). At T0,T1,T4,there was no statistical significance in VAS score between 2 groups(P>0.05). VAS scores of 2 groups at T2-3 were significantly higher than at T0,T1,T4,with statistical significance(P0.05). There was no statistical significance in diastolic pres-sure,RR and SpO2 between 2 groups at T0-2(P>0.05). The systolic pressure of 2 groups at T3-4 were significantly higher than at T0, with statistical significance(P0.05). There was no statisti-cal significance in the levels of IL-6,IL-8,CRP or PRL between 2 groups at T0(P>0.05). The levels of IL-6,IL-8 and CRP in 2 groups at T3 were significantly higher than at T0,but the observation group was significantly lower than the control group;at T4,the levels of IL-6,IL-8 and CRP in control group were significantly higher than at T0,with statistical significance(P0.05). The levels of PRL in 2 groups at T3-4 were significantly higher than at T0,and increased gradually as time;the observation group and significantly higher than the control group,with statistical significance (P<0.05). The incidence of ADR in observation group was significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:For maternal after cesarean section,nalbuphine is similar to mor-phine in analgesic effect and cardiovascular effect,but it is better than morphine in reducing inflammatory level,promoting lacta-tion and safety.
ABSTRACT
Objective To investigate the effects of programmed intermittent epidural bolus (PIEB) with continuous epidural infusion (CEI) at different time intervals for epidural labor analgesia.Methods One hundred and eighty-six nulliparous parturients were randomized to the groups P1, P2 and C.Epidural infusion was given initial loading dose: 10 ml (0.125% ropivacaine with 0.4 μg/ml sufentanil), followed by maintaining dose: 0.08% ropivacaine with 0.4 μg/ml sufentanil.Group P1 was given basal infusion 5 ml per 30 min, 30 min after the initial dose;group P2 was given basal infusion of 10 ml per 60 min, 60 min after the initial dose;CEI basal infusion of 10 ml/h immediately after the initial dose;PCEA (patient-controlled epidural analgesia dose) 5 ml (lockout interval: 30 min).The baseline maternal heart rate, noninvasive arterial blood pressure, SpO2, respiratory rate, and fetal heart rate tracing were recorded.The visual analog scale (VAS) was recorded during the first stage of labor and at full cervical dilation.The degree of motor block was assessed in both lower extremities using the modified Bromage score (MBS).The maximum blocked segment, the consumption of anesthetic, delivery mode, amount of oxytocin, The number of cases of motor block and intrapartum fever, the fetal Apgar scores,adverse reactions,maternal satisfaction score were recorded.Results The VAS obviously decreased in the three groups since receiving labor analgesia (P<0.05).The ratio of VAS score more than 3 scales in group PIEBⅡ was significantly lower than that in groups P1 and C (P<0.05).The maximum blocked segment increased in group P1, while The incidence of unilateral block was significantly decreased in group P2 (P<0.05).The total drug consumption.And the toatal number of PCA were decreased obviously in group PIEB (P<0.05).The initial PCA time was significantly prolonged in group P2 (P<0.05).The number of instrumental midwifery and intrapartum fever in group P2 were significantly lower than that in group C (P<0.05).Conclusion Programmed intermittent epidural bolus at the beginning 60 min intervals after the initial dose for epidural labor analgesia is scientific and effective.
ABSTRACT
Background: PCEA (patient controlled epidural analgesia) is a safe and effective technique for postoperative analgesia on routine surgical wards. Use of the epidural catheter as part of a combined epidural-general anesthetic technique results in less pain and faster patient recovery immediately after surgery than general anesthesia followed by systemic opioids does. Aim: In this prospective, randomized, double – blind study, we compared the analgesic effectiveness, hemodynamic changes and other side effects of epidural analgesia with drug combination – bupivacaine with fentanyl and ropivacaine with fentanyl in different concentrations. Material and methods: It was a prospective, randomized, double – blind study. Sixty patients of ASA I-II and age group 18-65 years divided in four groups 15 patients in each group (Group B1 bupivacaine 0.1%; Group B2 bupivacaine 0.05%; Group R1 ropivacaine 0.1%; Group R2 ropivacaine 0.05% with fentanyl 5micrograms/ml in each groups). After taking consent from patients epidural catheter was placed and study drugs were given to every patient. Visual analogue scale, heart rate, Jain R, Gupta P, Jain V. A comparison of ropivacaine with fentanyl to bupivacaine with fentanyl for post-operative patient controlled epidural analgesia in patients undergone lower abdominal cancer surgery. IAIM, 2016; 3(7): 137-149. Page 138 blood pressure, sedation score, modified bromage scale and other side effects were noted for the next 48 hours. Statistical analysis was done by using Medcalc 12.2.1.0 version statistical analysis software. Results: All four groups were comparable in terms of analgesia but group B1 patients had significant decrease in blood pressure at all time intervals. This group also had loss in motor power of lower extremity p value 0.020 than all other three groups. Conclusions: We concluded that ropivacaine 0.1% with fentanyl 5 µg/mL after major abdominal surgery provides optimal dynamic analgesia without significant adverse effects.
ABSTRACT
Objective: To investigate the effect of different analgesia methods on blood coagulation in patients who underwent esophageal carcinoma surgery through thrombelastography (TEG). Methods:A total of 60 patients who underwent radical esophagecto-my were randomly divided into the patient-controlled epidural analgesia (PCEA) group and patient-controlled intravenous analgesia (PCIA) group with 30 cases each. The visual analogue scale (VAS) and patient-controlled analgesia (PCA) bottom pressing times were recorded at 6, 12, 24, and 48 h after surgery. The TEG parameters were measured at the time before anesthesia (T0), the end of surgery (T1), first day after operation (T2), second day after operation (T3), and third day after operation (T4). Results:(1) Compared with the PCIA group, the VAS scores and PCA bottom pressing times were significantly lower (P0.05), and were significantly prolonged than those in the PCIA group at T2, T3, and T4 (P<0.05). (3) The platelet amount of the two groups decreased at T2 and T3 compared with that at T0 (P<0.05). Conclu-sion:The analgesic effect of PCEA was better than that of PCIA in patients who underwent esophageal carcinoma surgery, and may im-prove their hypercoagulability.
ABSTRACT
ObjectiveTo investigate the effect of patient-controlled epidural analgesia(PCEA) with opioids on serous myelin basic protein(MBP) and somatosensory evoked potential(SEP) of lower limbs in puerperants.MethodsA total of 120 puerperants,after receiving cesarean section,were divided into four groups by random number table method as group B,BR,MR and R randomly,and each group included 30 cases.After surgery,each case received PCEA:group B received 0.008％ butrophanol;group BR received 0.008％ butrophanol + 0.2％ ropivacaine;group MR received 0.004％ morphine +0.2％ ropivacaine and group R received 0.2％ ropivacaine only.VAS score,OAA/S score,adverse effect occurrence,concentration changes of serous MBP,SEP of both lower limbs and neurological function were observed at 2h(T1 ),4h(T2),8 h(T3),12h(T4),24 h(T5) and 48h (T6) after surgery.ResultsVASscoresofgroupBR(1.64±0.38,1.86±0.62,1.93±0.67) and MR( 1.74 ±0.39,1.91±0.58,1.98 ±0.63) at T3,T4,T5 were lower than those of group B(4.6 ±0.5,4.6 ±0.3,4.7 ±0.3)and R(2.64 ±0.41,2.83 ±0.91,3.37 ±0.87) (P＜0.05).There was no significance in four groups in OAA/S score at each point (P ＞ 0.05 ).Incidence of nausea ( 6 cases),vomiting ( 2 cases) and abdominal distention ( 5cases) of group M was higher than that of other three groups(P＜0.05).There was no significant difference in concentrations of serous MBP,SEP and neurological function in all four groups between preoperative time and 48h after operation(P＞0.05).ConclusionLower-dose and lower- concentration opioids used for PCEA have no influence on serum MBP and SEP.
ABSTRACT
PURPOSE: Total knee replacement is one of the most painful orthopedic procedures, and effective pain relief is essential for early mobility and discharge from hospital. The aim of this study was to evaluate whether addition of single-injection femoral nerve block to epidural analgesia would provide better postoperative pain control, compared to epidural analgesia alone, after total knee replacement. MATERIALS AND METHODS: Thirty-eight patients received a single-injection femoral nerve block with 0.25% levobupivacaine (30 mL) combined with epidural analgesia (femoral nerve block group) and 40 patients received epidural analgesia alone (control group). Pain intensity and volume of patient-controlled epidural analgesia medication and rescue analgesic requirements were measured in the first 48 hours after surgery at three time periods; 0-6 hours, 6-24 hours, and 24-48 hours. Also, side effects such as nausea, vomiting, and pruritus were evaluated. RESULTS: Median visual analog scale at rest and movement was significantly lower until 48 hours in the femoral nerve block group. Patient-controlled epidural analgesia volume was significantly lower throughout the study period, however, rescue analgesia requirements were significantly lower only up to 6 hours in the femoral nerve block group. The incidences of nausea and vomiting and rescue antiemetic requirement were significantly lower in the femoral nerve block group up to 6 hours. CONCLUSION: The combination of femoral nerve block with epidural analgesia is an effective pain management regimen in patients undergoing unilateral total knee replacement.

BACKGROUND:Hydromorphone is a semi-synthetic opioid that has recently been used for the control of acute and chronic pain.It has been reported that epidural infusion of hydromorphone provides rapid onset of analgesia and a lower incidence of side effects than morphine.However, comparative studies of hydromorphone and lipophilic opioids such as fentanyl are rare.Therefore, we compared the analgesic effects and side effects of hydromorphone infused epidurally with fentanyl in patients who underwent total knee arthroplasty. METHODS:In a randomized, double-blind manner, 79 patients (ASA I-III, aged 60?75) underwent total knee arthroplasty and were provided with patient-controlled epidural analgesia (PCEA) using a lumbar spinal/epidural-combined technique. Group HR (n = 39) received epidurally administered hydromorphone (4microg/ml) with 0.1% ropivacaine, while group FR (n = 40) received epidural fentanyl (2microg/ml) with 0.1% ropivacaine for 24 h after surgery at a rate of 5 ml/h. The visual analogue scale (VAS) was used to evaluate pain and the incidence of side effects such as nausea/vomiting, pruritis, dizziness, and respiratory depression were recorded at 4, 8, 12, 24 h after surgery. RESULTS:Group HR showed a lower VAS than group FR at 4, 12 and 24 h after surgery, but a higher incidence of nausea and vomiting at 8 h after surgery, and a higher incidence of pruritis at 8 and 12 h after surgery. None of the patients showed respiratory depression. CONCLUSIONS:Lumbar epidural infusion of hydromorphone more effectively controlled acute pain after total knee arthroplasty when compared with fentanyl, but some adverse effects such as nausea and vomiting appeared to occur more frequently.

BACKGROUND: Midazolam has been reported to have a spinally mediated antinociceptive effect. In this randomized, double-blind study, we evaluated whether a small dose of midazolam added to fentanyl-ropivacaine mixture for PCEA (patient controlled epidural analgesia) improves epidural analgesia in patients underwent elective subtotal gastrectomy. METHODS: Forty five patients, ASA physical status I and II, undergoing subtotal gastrectomy were randomly allocated to receive 0.2% ropivacaine mixed with fentanyl 4microg/ml or 0.2% ropivacaine mixed with fentanyl 4microg/ml and midazolam 0.2 mg/ml. The infusion rate was set to deliver 4 ml/hr of the study solution, with a bolus of 2 ml per demand and a 20 minutes lockout time. RESULTS: Infused volume (P < 0.05) and VAS scores (P < 0.05) was significantly lower in the patients receiving midazolam. However, there were no differences in requiring rescue analgesics, PONV (postoperative nausea and vomiting), sedation scores, urinary retention, and pruritus between groups. CONCLUSIONS: Small dose of midazolam could augment analgesia without adverse effects when added to thoracic epidural infusion of fentanyl and ropivacaine.

Objective:To evaluate the curative effects of patient controlled epidural analgesia(PCEA)for symptomatic lumbar disc herniation.Methods:Lumbar disc herniation cases(n=98)were divided into two groups.The epidural drugs injection group(DEDI group,n=54)underwent the epidural drugs injection 4 times as one treatment course.The patient controlled epidural analgesia group(PCEA group,n=44)underwent the same treatment,but the first epidural drugs injection was followed by PCEA for 7 days.Evaluate the curative effects and the side effects.Results:VAS scores in both groups decreased significantly on the eighth day and at the end of the treatment,being 4.41?0.62 and 1.30?0.77 in the PCEA group and 5.09?0.88 and 1.65?0.97 in the DEDI group(P0.05).No significant side effect was found during the treatment.Conclusion:PCEA is an effective method of lumbar disc herniation,and it relieves the symptoms and signs more quickly in the early treatment compared with the DEDI.
ABSTRACT
BACKGROUND: Low-dose intrathecal opioid has been used for early postoperative pain co1ntrol. This study was designed to assess effect intrathecal morphine on postoperative pain control for total knee arthroplasty (TKA) under combined spinal-epidural analgesia (CSE) in elderly patients. METHODS: Fifty four patients over 60 years, undergoing TKA were randomly allocated to three groups. M(0) group for control group did not received intrathecal morphine, M(50) and M(100) group received intrathecal morphine 50microgram and 100microgram respectively. The pain scores (verbal numeric rating scale, VNRS) at rest and coughing, analgesic consumption, patient satisfaction and side effects such as nausea, vomiting, pruritus, headache, dizziness, sedation, respiratory depression, and urinary retention were recorded immediately before and at 1, 3, 6, 12, 24, 48 hour after the initiation of patient-controlled epidural analgesia (PCEA). RESULTS: VNRS were low at each time, and were not exceeding 2 in all groups. M(50) and M(100) group revealed significantly less analgesic consumption compared to M(0) group (P < 0.05). PCEA first injection time after PCEA connection was shortest in M(0) group compared to M(50) and M(100) group. The incidence of pruritus increased in M(50) and M(100) group with dose-dependence, but no significant differences were noticed in other side effects. CONCLUSIONS: Intrathecal morphine use showed no significant analgesic effect except pruritus compared to control group. Further studies are required into the effective intrathecal morphine without side effects in elderly patients for TKA.

ABSTRACT
@#ObjectiveTo compare the effect of patient-controlled epidural analgesia (PCEA) and patient-controlled intravenous analgesia (PCIA) on pulmonary function in post-thoracotomy patients.Methods33 ASA Ⅰ～Ⅱ patients undergoing selective esophagectomy were randomly divided into the PCEA group (n=16, treated with morphine plus bupivacaine) and PCIA group (n=17, treated with morphine plus droperidol) for 3 days postoperatively. Pulmonary function indices including respiratory rate (RR), tidal volume (Vt), vital capacity (Vc) and pulse oximetry (SpO2) were recorded before operation and on the first 2 days after operation. Pain scores with visual analogue scale (VAS) at rest, deep breathing and with cough, and adverse effects were also recorded.ResultsRR increased, Vt , Vc and SpO2 decreased markedly in both groups postoperatively compared with the base line (P<0.01), but there were no significant differences between two groups. VAS scores were much lower in PCEA group, especially, when the patient was at deep breathing or during coughing (P<0.001).ConclusionPCEA is superior to PCIA in pain relief, but contributes no more than PCIA in improving pulmonary function in post-thoracotomy patients.
ABSTRACT
BACKGROUND: The aim of this randomized double-blinded study was to determine the optimal concentration of alfentanil with 0.15% ropivacaine for postoperative patient-controlled epidural analgesia. METHODS: Forty five patients undergoing major abdominal surgery under general anesthesia were assigned to groups receiving patient-controlled thoracic epidural analgesia with 0.15% ropivacaine + 45 microgram/ml alfentanil (Group I), 75microgram/ml alfentanil (Group II), 150 microgram/ml alfentanil (Group III). The incidence of side effects and additional analgesic use, VAS (visual analog pain scale) on resting and coughing, and patient's satisfaction were checked for 24 hours after a loading dose injection. RESULTS: The VAS on coughing and resting 1 hour after the loading dose injection were significantly lower in Groups II and III than in Group I. The patients in group II were more satisfied with the result than those in Group I. CONCLUSIONS: A combination of 0.15% ropivacaine and 75microgram/ml alfentanil for thoracic epidural analgesia after major abdominal surgery provides the best analgesia with minimal side effects and a higher level of patient's satisfaction.

BACKGROUND: Patient-controlled epidural analgesia (PCEA), using a local anesthetic-opioid mixture, has been effectively applied after total knee replacement (TKR) surgery, which is associated with intense postoperative pain that requires postoperative analgesia for both rehabilitation and the pain itself. However, adverse opioid-related effects, such as nausea, vomiting and pruritus, are commonly encountered. It was our hypothesis that the adverse opioid-related effects could be reduced by the addition of naloxone, an opioid antagonist, to a mixture of fentanyl-ropivacaine PCEA. METHODS: In 120 patients undergoing elective TKR surgery, epidural or combined spinal-epidural (CSE) anesthesia was performed and PCEA applied. In the control group (n = 65), 0.16% ropivacaine and 3microgram/ml fentanyl (2.4microgram/ml for those older than 65 yrs) were administered. In the naloxone group (n = 55), naloxone (2microgram/ml) was coadministered with the above regimen. The incidence and severity of postoperative nausea and vomiting, and the frequency of pruritus, the visual analog score (VAS) and the PCEA volume used were assessed 6 and 24 hrs after surgery. RESULTS: The incidence of nausea and vomiting during the early postoperative period, and those of pruritus during the late postoperative period were significantly lower in the naloxone group. The VAS pain scores, the PCEA volume used and amount of rescue IV meperidine were similar in the two groups. CONCLUSIONS: A small dose of naloxone mixed with an opioid significantly reduces the incidence and severity of adverse opioid-related effects in PCEA, without reducing the analgesic effect

Complex regional pain syndrome (CRPS) is a syndrome of pain and sudomotor or vasomotor instabilities. The perioperative pain management in CRPS patients is very important, as surgery can aggravate preexisting symptoms, especially when performed around the lesion site. Despite the increasing interest in CRPS research, little is known about the optimal perioperative treatment strategy for CRPS patients. Herein, the case of a female CRPS patient, who underwent elective surgery at the lesion site, is reported. As a preemptive analgesia, the patient was satisfactorily managed with two weeks of patient-controlled epidural analgesia, initiated 2 days prior to surgery. The techniques for the prevention of perioperative pain, including preemptive analgesia, as well as its importance, are discussed.
