ABSTRACT
BACKGROUND: Prolonged motor and sensory block following Central Neuraxial Blockade (CNB) is associated with extended postoperative immobilization and its complications. Speedy recovery from motor blockade would improve the patients' acceptance of neuraxial anesthesia. Previous studies in patients undergoing epidural anaesthesia, demonstrated rapid motor recovery after administration of epidural crystalloids. We studied the effect of intermittent bolus injection of Normal saline (NS) on the duration of sensory and motor recovery after Combined spinal epidural anaesthesia (CSEA). METHODS:60 patients (ASA I-III) scheduled for surgeries under CSEA lasting for 1½ to 2 hrs were divided equally by systematic random sampling at the end of surgery. Control group - No bolus of NS flush was given through the epidural catheter. Intervention group -15 ml of NS flush through epidural catheter was given thrice. Sensory level, Motor blockade and vitals were noted at 5 min interval for 2 hours from end of surgery. RESULTS: 1. Sensory levels in two groups were significantly different (p-value < 0.001) at the end of two hours. In intervention group, T8 level was predominant, while in control group L1 level was predominant. 2. Difference in motor block in two groups was significant as (p-value < 0.001). In intervention group, 86.67% had Bromage score 0, while in control group 80% had score 1 at the end of 2 hrs. Conclusion: Postoperative epidural flush with 45 ml Normal saline hastened the motor recovery following CSEA without shortening of the duration of sensory blockade.
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 explore the correlation of patient-controlled sedation of dexmedetomidine and Narcotrend values. Methods Forty patients with lower limb surgery were enrolled. Until CSEA block fixed , the electronic pump ran the patient-controlled sedation of dexmedetomidine. The parameter of electronic pump was set as follows: load dose 2 mL + background dose 1.5 mL/h + single dose 0.5 mL + locktime 20 s. The heart rate , mean arterial pressure, pressing times, effective times, OAA/S sedation scores and NI values were determined. Results At T4 point, the patients reached appropriate sedation. At T4 ~ T9 OAA/S scores kept 3 to 4. From T5 point, NI values showed significant decrease. After the T7 point. OAA/S scores and NI values reached the plateau time of (7.5 ± 1.8) min and (13.1 ± 3.4) min, OAA/S scores of 1, 2, 3, 4, respectively, corresponding roughly with NI values 95 to 100, 90 to 94, 65 to 89, 40 to 64. The correlation coefficient was 0.58. The time of NI values significant decreased in the younger group and in the elderly group, with (10.2 ± 1.6) min and (14.4 ± 2.2) min. In T5~ T9 point, NI values of the younger group were significantly lower than those in the elderly group. Conclusion Relevant relationships are observed between dexmedetomidine patient-controlled sedation depth and the narcotrend values under CSEA.
ABSTRACT
ObjectiveTo evaluate the effect of labor analgesia and the outcome of maternals and neonatals by applying the vitamin B6- folic acid mixture to combined with spinal-epidural analgesia(CSEA) in nulliparous women at latency.MethodsAll the 112 full-term nulliparous parturients were selected and divided into the treated group and controlled group.Nulliparous women in two groups received CSEA,with which the additional vitamin - folic acid mixture was used only in treatment group.The contrast between the analgesic effect in groups,and alalgesic effect-acting period,fentanyl Apgar score and newborn usage were compared between groups also.ResultsThe analgesic effect-acting period and fentanyl dosage in the treated group were significantly decreased.There was significant difference between the 2 ( P ＜ 0.05 ).ConclusionsIt could be effective applying vitamin B6- folic acid mixture at latency in nulliparous women based on CSEA,which could shorten the lumbar hemp effect-acting period and reduce fentanyl narcotic drugs dosage.
