BackgroundPain is a major problem in patients after cesarean and medication such as aromatherapy which is a complementary therapy, in which the essences of the plants oils are used to reduce such undesirable conditions.ObjectivesIn this study, the effect of aromatherapy using Lavender (Lavandula) essential oil on cesarean postoperative pain was assessed.Materials and MethodsIn a triple blind, randomized placebo-controlled trial study, 60 pregnant women who were admitted to a general hospital for cesarean section, were divided randomly into two groups. After cesarean, the Lavender group inhaled about 3 drops of 10% Lavender oil essence and the placebo group inhaled 3 drops of placebo after the start of postoperative pain, four, eight and 12 hours later, for 5 minutes from the 10 cm distance. Patient's pain was measured by the VAS (Visual Analog Scale) score before and after each intervention, and vital sign, complications and level of satisfaction of every patient were recorded before and after aromatherapy.ResultsThere was no statistically significant difference between groups in age, height, weight, and time to the first analgesic requirement. Patients in the Lavender group had less postoperative pain in four (P = 0.008), eight (P = 0.024) and 12 (P = 0.011) hours after first medication than the placebo group. The decreased heart rate and patients' level of satisfaction with analgesia were significantly higher in the Lavender group (P = 0.001). In the placebo group, the use of diclofenac suppositories for complete analgesia was also significantly higher than the Lavender group (P = 0.008).ConclusionsThe inhaled Lavender essence may be used as a part of the multidisciplinary treatment of pain after cesarean section, but it is not recommended as the sole pain management.
BackgroundEpidural block approach and drugs are common options for improving the sensory and motor block duration and postoperative pain management.ObjectivesThe study aimed to compare the analgesic effects of dexmedetomidine and morphine as adjuvants to bupivacaine for epidural anesthesia in leg fracture surgery.MethodsThis prospective clinical trial was conducted on patients (n = 80, age range: 18 - 60 years) categorized as ASA class I or II. After a clinical examination, the patients were allocated to receive either lumbar epidural bupivacaine + morphine (BM) (12 mL bupivacaine 0.5% + morphine 2 mg) or bupivacaine + dexmedetomidine (BD) (12 mL bupivacaine 0.5% + dexmedetomidine 1 µg/kg). After drug administration, the sensory block level was assessed at 2-min intervals using the Cold Swab method until it reached the T12 level. At the T12 level of sensory block, the surgery began when motor block reached grade 3 of the modified Bromage scale.ResultsThe BD group had a significantly shorter time to reach the sensory and motor block than the BM group (P < 0.001). The duration of sensory and motor block was significantly longer in the group BD than in the BM group (P < 0.001). Moreover, the BD group showed lower VAS scores (P < 0.0001) and longer time to first analgesia demand than the BM group.ConclusionsCombined bupivacaine + dexmedetomidine prolongs the sensory and motor block duration and controls postoperative pain more effectively, indicating that it is an appropriate combination for epidural anesthesia.
Background: Spinal anesthesia is the most common technique used for cesarean delivery due to some advantages compared to regional anesthesia. It is easily performed and provides a rapid onset of block. Though bupivacaine is a generally used long-acting amide type local anesthetic drug for spinal anesthesia, ropivacaine may sometimes be selected. Objectives: This prospective, randomized, double-blinded study was aimed at comparing clinical efficacy and safety between ropivacaine and bupivacaine during cesarean section. Methods: After getting ethical committee approval and written informed consent, 65 women who referred to Imam Khomeini Hospital of Ahvaz, Iran in 2018 were chosen for elective cesarean delivery under spinal anesthesia. They were randomly allocated to receive either ropivacaine 1% (n = 33) or bupivacaine 0.5% (n = 32). Afterwards, the differences in the anesthetic efficacy, vital signs, and hemodynamics of participants between the two groups were recorded. Results: Duration of sensory block was shorter in the ropivacaine group than bupivacaine group (132.5 ± 21.6 min vs. 175.8 ± 26.2 min; P < 0.001). Ropivacaine also produced a shorter duration of motor blockade than bupivacaine (124.8 ± 20.2 min vs. 168.2 ± 21.7 min; P < 0.001). There is no difference between the two groups in terms of systolic and diastolic blood pressure, but the heart rate of patients in the bupivacaine group is significantly higher than the ropivacaine group. Conclusions: The results suggest that ropivacaine and bupivacaine are two efficient drugs in anesthesia in the cesarean section, ropivacaine is a better choice due to little influence on the hemodynamics and shorter duration of sensory block and motor block which are useful for the recovery and also safe to the patients.
BackgroundTo improve the brachial plexus block (BPB) performance, different compounds have been used as adjuvants to local analgesics.ObjectivesThe aim of the present study was to investigate the effects of adding DEX to lidocaine on effectiveness of nerve block, and postoperative pain in forearm fracture surgery by supraclavicular BPB undergoing ultrasound-guided.MethodsThis was a double-blinded randomized clinical trial conducted on 72 patients with ASA classes I and II, which were candidates for forearm fracture surgery. In group A, patients received 3 mg/kg of lidocaine 2%. In group B, patients received 3 mg/kg of lidocaine 2% and DEX (1 µg/kg). The ultrasound-guided supraclavicular BPB was performed in all patients. The onset of sensory and motor blocks were evaluated with pin prick test and modified Bromage scale, respectively. The sensory and motor block moment was recorded as the onset of the block. The first analgesic request time, total consumed analgesic, adverse effect, and hemodynamic parameters of patients were recorded. A visual analog scale (VAS) was used for recording the severity of pain.ResultsThe two groups showed no significant difference in the demographic variables. The onset of sensory and motor block in the DEX groups was shorter. The duration of sensory and motor block, and analgesic request was significantly longer than the control groups. Total analgesic consumption 24 hours after surgery in the DEX groups was significantly lower. Moreover, hemodynamic status of patients in both groups was stable and no significant difference was observed between groups. This study showed that DEX, as an adjuvant to lidocaine, improve the characteristics of supraclavicular BPB and decrease the postoperative pain.
