Background. Parasternal block and transcutaneous electrical nerve stimulation (TENS) have been demonstrated to produce effective analgesia and reduce postoperative opioid requirements in patients undergoing cardiac surgery.Objectives. To compare the effectiveness of TENS and parasternal block on early postoperative pain after cardiac surgery.Methods. One hundred twenty patients undergoing cardiac surgery were enrolled in the present randomized, controlled prospective study. Patients were assigned to three treatment groups: parasternal block, intermittent TENS application, or a control group.Results. Pain scores recorded 4 h, 5 h, 6 h, 7 h, and 8 h postoperatively were lower in the parasternal block group than in the TENS and control groups. Total morphine consumption was also lower in the parasternal block group than in the TENS and control groups. It was also significantly lower in the TENS group than in the control group. There were no statistical differences among the groups regarding the extubation time, rescue analgesic medication, length of intensive care unit stay, or length of hospital stay.Conclusions. Parasternal block was more effective than TENS in the management of early postoperative pain and the reduction of opioid requirements in patients who underwent cardiac surgery through median sternotomy. This trial is registered with Clinicaltrials.gov numberNCT02725229.

Background: Transcutaneous electrical nerve stimulation(TENS) is an effective physiological intervention for people with stroke which aims at reducing muscle spasticity, enhancing muscle strength, and improving motor control and function. In view of the potentials to enhance greater cortical activation of the lesion side by eliciting spare neural pathways through bilateral intervention, this study examined whether the combined use of bilateral TENS (Bi-TENS) and task-oriented training (TOT) was superior to unilateral TENS(Uni-TENS)+TOT, placebo-TENS+TOT and no active treatment to improve the motor impairment of upper limb function in people with stroke. Method: There were 120 subjects with stroke(44 females, mean age=61.52±6.73 years, post-stroke duration=6.04±3.12years) being randomly allocated into 4 groups, including the Bi-group (n=30), Uni-group (n=30), placebo group (n=30) and control group (n=30). Subjects in the Bi-group, Uni-group and placebo group got 60 minutes TENS and TOT simultaneously per time for 20 times(3 times per week for 7 weeks). In the Bi-group, TENS stimulated the radial and median nerves of the bilateral upper limbs. In the Uni-group, TENS and placebo-TENS stimulated the affected and unaffected side, respectively. In the placebo group, placebo-TENS were placed on bilateral sides. In the control group, subjects did not receive any active treatment. Level of motor impairment was assessed by the Fugl-Meyer Assessment of Upper Extremity (FMA-UE). Result: The Bi-group had a significant greater improvement in FMA-UE than the Uni-group(mean change=2.02, p=0.005), placebo group (mean change=2.49, p=0.001) and control group(mean change=3.08, p<0.001) at post-intervention. The Bi-group(mean change=3.25, p<0.001) and Uni-group(mean change=1.23, p=0.015) showed a significant within-group improvement in FMA-UE since 10 sessions of treatment. No significant change was found in the placebo and control groups. Conclusion: Bi-TENS is superior to Uni-TENS, placebo-TENS and no active treatment in augmenting the recovery of upper limb motor impairment in people with chronic stroke.

Electrical Nerve Stimulation

Background: Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive pain therapy that uses the sensory effects of an electrical current applied to the skin. Some clinical studies demonstrated that this treatment helps to reduce acute and chronic pains, while others gave sometimes contradictory or uncertain conclusions about the performances of this strategy according to pathology classification. The purpose of this study is the development and evaluation of a new modulated version of transcutaneous electrical nerve stimulation called PWM-TENS. The principle is based on an automatic variation of the stimulation parameters (frequency, amplitude, duration, shape, cyclic ratio) according to the pain evolution. Methods: The study was a controlled clinical trial involving 15 participants, divided into 2 groups. The first experimental group performed modulated PWM-TENS electro-stimulation sessions applied to the painful areas 3 to 4 times a day, for one month. The second control group did parallel treatments by Placebo. The evaluation of the pain intensity is done with the Visual Analog Scale (EVA), the DN4 and SF36 questionnaires. Results: The tests and measurements with our embedded PWM-TENS technique demonstrated that we succeeded to increase the analgesic effect after stopping the stimulation and reduced the pain sensation by about 60%. An improvement in pain intensity scores and questionnaires (EVA, DN4), as well as the quality of life score (SF36), was observed. Also, a reduction of the treatment period from 3 to 1 month was also obtained. Conclusion: The first results clinically observed in the PWM-TENS technique are encouraging. The findings of this study confirm that this noninvasive strategy is suitable and useful for acute pains coming from the nociceptive, neuropathic and musculoskeletal origin. However, its efficiency is moderated and less adapted for low back pain. The experiments make it possible to estimate whether this modulated TENS method could improve existing anti-pain therapies, taking into account objective and subjective evaluation criteria. But this study must be followed by large population samples to answer all the problems of acute and chronic pains.

Individualized administration of opioids based on preoperative pain sensitivity may improve postoperative pain profiles. This study aimed to examine whether a predicted administration of opioids could reduce opioid-related adverse effects after gynecological surgery. Patients were randomized to the predicted group or control group. Participants received a preoperative sensory test to measure pressure pain thresholds. Patients were treated with a higher or lower (15 or 10 μg/mL) dose of fentanyl via intravenous patient-controlled analgesia. The opioid dose was determined according to pain sensitivity in the predicted group, while it was determined regardless of pain sensitivity in the control group. The primary outcome was the incidence of nausea over the first 48 h postoperative period. Secondary outcomes included postoperative pain scores and opioid requirements. There was no difference in the incidence of nausea (40.0% vs. 52.5% in predicted and control groups, respectively; p = 0.191) and postoperative pain scores (3.3 vs. 3.5 in predicted and control groups, respectively; p = 0.691). However, opioid consumptions were lower in the predicted group compared to the control group (median 406.0 vs. 526.5 μg; p = 0.042). This study showed that offering a predicted dose of opioids according to pain sensitivity did not affect the incidence of nausea and pain scores.

Objective. To examine the effectiveness of cryotherapy for reducing postoperative pain in patients who underwent exploratory laparotomy for gynecologic surgery. Materials and Methods. Patients who had indication for an exploratory laparotomy gynecologic procedure were selected by attending physicians to undergo abdominal surgery via low transverse skin incision. The participants were randomized into study and control groups with simple random sampling methods. Cold packs were applied at two hours after operation for 6 hours. The visual analog scale (VAS) score was recorded at two, 6, and 12 hours after operation. Result. One hundred cases were recruited and then divided into study and control groups equally. The mean age of both groups was 43 years. There was no difference in demographics data of both groups. Half of the participants in both groups underwent hysterectomies. At two hours after surgery, both groups had similar VAS scores. The study group had a lower VAS score at 6 and 12 hours after surgery than the control group with statistical difference. Morphine consumption within 24 hours after surgery in both the study and control groups was 2.8±3.4 and 3.0±4.4 mg, respectively, with no statistical difference. However the registration time of the first morphine requirement in the study group was statistically more prolonged than that of the control group. The lengths of hospital stay in both groups were similar. There was no complication reported in this study. Conclusion. Cryotherapy can reduce postoperative pain. In this presented study the patients who underwent gynecologic surgery had improved pain relief and prolonged time for the first dose of the analgesic drug.

In prospective, random assignment of 2 groups of 15 patients, relief of postoperative pain with narcotic medications was evaluated and compared with transcutaneous electrical nerve stimulation (TENS) for 2 days immediately following surgery. Presence of ileus and hospital stay were identifical in both groups. Patients on TENS demonstrated a marked significant decrease in the amount of narcotics administered. There was favorable nursing, physician and patient acceptance to these devices. Further clinical evaluation is, therefore, in progress.
