Manual acupuncture for analgesia during electromyography: a pilot study. / Smith MJ, Tong HC. |
| Abstract |
OBJECTIVES: To evaluate the analgesic effect of acupuncture for needle electromyography and to validate a sham acupuncture needle. DESIGN: Randomized, double-blinded, controlled study. SETTING: University-based electrodiagnostics laboratory. PARTICIPANTS: Fifty-one subjects referred for electrodiagnostic evaluation. INTERVENTIONS: Before the electromyography examination, either real acupuncture needles or telescopic sham needles were applied. MAIN OUTCOME MEASURES: Visual analog scale of pain and unpleasantness after 3 muscles were examined with electromyography. Pretest pain was subtracted to give a measurement of pain attributable to the electromyography. Subjects were asked which needle they thought they had received. RESULTS: Twenty-six subjects were randomized to the treatment group and 25 to the sham group. Pain in the treatment group (-.96) was less than in the control group (9.68), but it was not statistically significant (P=.13). Post hoc analysis, excluding 5 subjects known to have been treated by the novice acupuncturist, showed a significant difference of 14.4mm (P=.02). The proportion of subjects who thought they received real needles in the acupuncture group (69%) did not differ from the proportion in the control group (48%) (P=.13). CONCLUSIONS: Acupuncture may represent an effective form of analgesia for electromyography. This is the first study to suggest independently the telescopic sham acupuncture needle as an effective control. |

The effect of ting point (tendinomuscular meridians) electroacupuncture on thermal pain: a model for studying the neuronal mechanism of acupuncture analgesia. / Leung A, Khadivi B, Duann JR, Cho ZH, Yaksh T. |
| Abstract |
Objective: The aim of this study was to characterize the role of Ting points (TP) in acute pain management and its potential use in functional imaging studies by quantitatively assessing: (1) the change in peripheral thermal thresholds before and after the electroacupuncture (EA); and (2) the corresponding behavioral feedback of thermal pain stimulation and the de qi sensation of EA. Design: The study design was prospective. Settings/location: Healthy subjects were recruited for the study at the University of California, San Diego Medical Center. Subjects/interventions: Thirteen (13) healthy subjects were studied. Baseline thermal thresholds (cold and warm sensations and cold and hot pain) were measured at premarked testing sites along the medial aspects of bilateral lower extremities. Five (5) seconds of hot pain (HP) was delivered to the testing sites and the corresponding pain visual analog scale (VAS) scores were recorded. Thirty (30) seconds of EA was delivered via the SP1 and LR1 on the left lower extremities at 5 Hz via a 6-V square-wave stimulator. Outcome measures: The VAS scores of the HP and de qi sensation (tingling) during the EA were recorded. The thermal thresholds and VAS scores for the HP and de qi were obtained immediately and both 30 and 60 minutes after the EA. Adaptation testing was also carried out to assess the change in thermal thresholds and the VAS scores of HP without EA. Results: The warm thresholds of bilateral medial calves significantly increased (p < 0.01) after 30 seconds of EA stimulation. The HP VAS score reduced significantly at the ipsilateral calf during EA in comparison to preacupuncture and postacupuncture (p < 0.01) measurements. No significant change in thermal thresholds was noted in the adaptation paradigm. Conclusions: EA at the TP has an inhibitory effect on the C-fiber afferents. The analgesic benefit observed is most likely A-delta afferent mediated. Further correlation studies in functional imaging may provide defining data for the observed analgesic mechanism. |

Conscious sedation and analgesia for oocyte retrieval during in vitro fertilisation procedures. / Kwan I, Bhattacharya S, Knox F, McNeil A. |
| Abstract |
BACKGROUND: Various methods of sedation and analgesia have been used for pain relief during oocyte recovery in IVF/ICSI procedures. The choice of agents has also been influenced by quality of analgesia as well as by concern about possible detrimental effects on reproductive outcome. OBJECTIVES: To assess the efficacy of conscious sedation and analgesia versus alternative methods on pregnancy outcomes and pain relief in patients undergoing transvaginal oocyte retrieval. SEARCH STRATEGY: We searched the Specialised Register of the Menstrual Disorders and Subfertility Group, The Central Register of Controlled Trials (CENTRAL) , MEDLINE (1966 to present), EMBASE (1980 to present), CINAHL (1982 to present), the National Research Register, and Current Controlled Trials. There was no language restriction. All references in the identified trials and background papers were checked and authors contacted to identify relevant published and unpublished data. SELECTION CRITERIA: Only randomised controlled trials comparing conscious sedation and analgesia versus alternative methods for pain relief during oocyte recovery were included. DATA COLLECTION AND ANALYSIS: Two reviewers independently scanned abstracts of the reports identified by electronic searching to identify relevant papers, extracted data and assessed trial quality. Interventions were classified and analysed under broad categories/strategies of pain relief comparing conscious sedation/analgesia with alternative methods and administration protocols. MAIN RESULTS: Our search strategy identified 390 potentially eligible reports and 12 papers met our inclusion criteria. There were no significant differences in clinical pregnancy rates per woman and patient satisfaction between the methods compared. Women's perception of pain showed conflicting results. Due to considerable heterogeneity, in terms of types and dosages of sedation or analgesia used, and tools used to assess the principal outcomes of pain and satisfaction, a meta-analysis of all the studies was not attempted. Of the three trials which compared the effect of conventional medical analgesia plus paracervical block versus electro-acupuncture plus paracervical block, there was no significant difference in clinical pregnancy rates per woman in the two groups (OR 1.01; 95% CI 0.73 to 1.4). For intra-operative pain score as measured by visual analogue scale (VAS), there was a significant difference (WMD -4.95; 95% CI -7.84 to -2.07), favouring conventional medical analgesia plus paracervical block . There was also a significant difference in intra-operative pain by VAS between patient-controlled sedation and physician-administered sedation (WMD 5.98; 95% CI 1.63 to 10.33), favouring physician -administered sedation. However, as different types and dosages of sedative and analgesic agents were used in these trials, these data should be interpreted with caution.For the rest of the trials, a descriptive summary of the outcomes was presented. AUTHORS' CONCLUSIONS: There is insufficient evidence to determine the effect of different methods of pain relief when compared with conscious sedation and analgesia used during oocyte recovery. In this review, no one particular pain relief method or delivery system appeared to be better than the other. In future, greater consensus is needed to determine both the tools used to evaluate pain and the timing of pain evaluation during and after the procedure. Pain assessment using both subjective and objective measures may merit consideration. In addition, future trials should include intra- and post-operative adverse respiratory and cardiovascular events as outcomes. |

Acupuncture analgesia and its application in cranio-maxillofacial surgical procedures. / Pohodenko-Chudakova IO. |
| Abstract |
BACKGROUND: The present study investigated the use of acupuncture analgesia in maxillofacial surgery. PATIENTS AND METHODS: Acupuncture analgesia was applied in 120 patients. In 20 of these, surgery was carried out under general anaesthesia in combination with acupuncture analgesia. In 100 patients, acupuncture analgesia was applied in addition to traditional postoperative analgesia. In case of troublesome postoperative pain, it was necessary to carry out additional sessions (1-4) of acupuncture stimulation. RESULTS: When acupuncture analgesia was used, the pulse rate and blood pressure during surgery generally remained stable. In the present study serum cortisol was also measured and showed only minor elevation. DISCUSSION: The present study demonstrated favourable results when the first variant of the brake method of acupoint stimulation was used for 40-50 min with additional manual twirling of the needles. This involved inserting needles into the acupoints and, using slow, rolling manual movements increasing the amplitude step-by-step provoking simultaneous especially strong patient sensations. CONCLUSION: Acupuncture analgesia can be a useful adjunct to conventional anaesthesia in maxillofacial surgery. |

Analgesic effect of auricular acupuncture for cancer pain: a randomized, blinded, controlled trial. / Alimi D, Rubino C, Pichard-Leandri E, Fermand-Brule S, Dubreuil-Lemaire ML, Hill C. |
| Abstract |
PURPOSE: During the last 30 years, auricular acupuncture has been used as complementary treatment of cancer pain when analgesic drugs do not suffice. The purpose of this study is to examine the efficacy of auricular acupuncture in decreasing pain intensity in cancer patients. PATIENTS AND METHODS: Ninety patients were randomly divided in three groups; one group received two courses of auricular acupuncture at points where an electrodermal signal had been detected, and two placebo groups received auricular acupuncture at points with no electrodermal signal (placebo points) and one with auricular seeds fixed at placebo points. Patients had to be in pain, attaining a visual analog score (VAS) of 30 mm or more after having received analgesic treatment adapted to both intensity and type of pain, for at least 1 month of therapy. Treatment efficacy was based on the absolute decrease in pain intensity measured 2 months after randomization using the VAS. RESULTS: The main outcome was pain assessed at 2 months, with the assessment at 1 month carried over to 2 months for the eight patients who interrupted treatment after 1 month. For three patients, no data were available because they withdrew from the study during the first month. Pain intensity decreased by 36% at 2 months from baseline in the group receiving acupuncture; there was little change for patients receiving placebo (2%). The difference between groups was statistically significant (P <.0001). CONCLUSION: The observed reduction in pain intensity measured on the VAS represents a clear benefit from auricular acupuncture for these cancer patients who are in pain, despite stable analgesic treatment. |
