The use of low-intensity laser irradiation in the immediate postoperative period in patients with gastroduodenal ulcer]

In patients with an ulcer of the stomach and duodenum at the immediate postoperative period in the complex of treatment, the low intensity laser irradiation of the anastomosis (after gastric resection) and ulcer (after the organ-preserving operations) according to the developed method by means of the modified LG-75 apparatus was used. The use of a helium-neon laser contributed to development of the severe form of anastomositis and subsequent gastrostasis. In study of gastric secretion, no considerable changes in acid formation were revealed.     

P6 acupressure does not prevent emesis during spinal anesthesia for cesarean delivery

Nausea and vomiting are major adverse effects during spinal anesthesia for cesarean delivery. Stimulation of the P6 (Neiguan) acupoint is a traditional Chinese acupuncture technique used for effective antiemetic purposes. In this study, we evaluated the antiemetic effect of P6 acupressure in parturients during spinal anesthesia for cesarean delivery. In a randomized, double-blind, controlled trial, 110 parturients scheduled for elective cesarean delivery were enrolled in the study. Thirty minutes before initiation of spinal anesthesia, parturients were randomized to acupressure bands or placebo bands bilaterally on the P6 acupoint and nausea and vomiting were observed over the study period. There were no statistically significant differences in maternal characteristics. Incidence rates for intraoperative nausea were 64% (acupressure group) and 71% (control group) (P = 0.416), with an incidence of intraoperative vomiting of 22% (acupressure group) and 27% (control group) (P = 0.506). The results suggest that prophylactic use of acupressure bands bilaterally on the P6 acupoint failed to prevent nausea and vomiting during spinal anesthesia for cesarean delivery.     

Korean hand acupressure reduces postoperative nausea and vomiting after gynecological laparoscopic surgery

To investigate the effectiveness of prophylactic Korean hand acupressure in the prevention of postoperative vomiting in women scheduled for minor gynecological laparoscopic surgery, we conducted a double-blinded, randomized, placebo-controlled study. In one group (n = 40), acupressure was performed 30 min before the induction of anesthesia by using special acupressure seeds, which were fixed onto the Korean hand acupuncture point K-K9 and remained there for at least 24 h. The second group (n = 40) functioned as the Placebo group. The treatment groups did not differ with regard to demographics, surgical procedure, or anesthetic administered. In the Acupressure group, the incidence of nausea and vomiting was significantly less (40% and 22.5%) than in the Placebo group (70% and 50%). We conclude that Korean hand acupressure of the acupuncture point K-K9 is an effective method for reducing postoperative nausea and vomiting in women after minor gynecological laparoscopic surgery. IMPLICATIONS: This randomized study was performed to investigate the antiemetic effect of the Korean hand acupuncture point K-K9. Acupressure of K-K9 reduces the incidence of postoperative nausea and vomiting in female patients after minor gynecological laparoscopic surgery.

Comparison of laser acupuncture and metoclopramide in PONV prevention in children

BACKGROUND: Postoperative nausea and vomiting (PONV) are frequent side effects of general anesthesia in children. The aim of this study was to compare the effectiveness of laser acupuncture with metoclopramide in prevention of PONV in children after sevoflurane anesthesia. METHODS: A total of 120 children ASA I and II, scheduled for hernia repair, circumcision or orchidopexy were randomly assigned into three groups: group I, received laser acupuncture on P6 point and saline infusion; group II, metoclopramide 0.1 mg.kg(-1) i.v. and sham laser; group III had sham laser and saline infusion. Anesthesia was maintained with sevoflurane and N(2)O/O(2). Patients were monitored for any symptoms of retching and vomiting at 2, 6 and 24 h postoperatively. RESULTS: The incidence of vomiting was higher in the control group in the first 2 h postoperatively (P < 0.001), compared with the other groups. There was no statistically significant difference between acupuncture and metoclopramide groups in occurrence and timing of vomiting (P < 0.001). CONCLUSION: Laser acupuncture is equally effective as metoclopramide in preventing PONV in children.     

An experimental study of the healing effect of the HeNe laser and the infrared laser

Changes in the macroscopic appearance and in the histological features of full-thickness, excised, circular wounds treated with either an infrared (IR) or a helium-neon (HeNe) laser were compared with those occurring in control wounds over a period of 15 days. The wounds were produced in the skin of the backs of anaesthetized adult female rats, and were initially 1 cm in diameter. The control and the two experimental laser-treated groups each consisted of ten wounds, one per rat. In the experimental groups either the IR laser was applied at 2.1 J/cm², 904 nm, 3500 Hz, for four min each day, or the HeNe laser was applied at 3.6J/cm², 632.8 nm, continuous, for eight min. The laser-treated wounds decreased in size and re-epithelialized more rapidly than did the controls. Qualitative histological examination indicated that periodic acid-Schiff-positive material decreased more rapidly in the laser-treated groups than in the controls. No significant differences in the effects of the two forms of laser treatment were found. The clinical significance of these observations is discussed.     

Acupuncture and kidney disease

Acupuncture as a complex therapeutic system has been used to treat a variety of diseases and pathological conditions. Although the exact mechanism(s) of acupuncture remains unknown, some evidence suggests a mechanism initially involving signal transduction through connective tissue, with secondary involvement of other systems including the nervous system. Acupuncture has become increasingly popular in the Western countries as a therapy for pain and several chronic disorders difficult to manage with conventional treatments. Acupuncture and acupuncture-like somatic nerve stimulation have been used in different kidney diseases and several complications related to them. The effect of acupuncture techniques in some kidney diseases is reviewed on the basis of clinical reports as well as mechanisms that may possibly explain the beneficial effects mediated by acupressure/acupuncture. The potential effect of acupressure techniques in renal inflammation and whether these effects could be mediated through the newly identified cholinergic anti-inflammatory pathway are discussed.     

Effect of helium-neon laser irradiation on serum lipid peroxide concentrations in burnt mice.

The effect of helium-neon irradiation on serum lipid peroxide concentrations in mice following 6-7% body surface area burns was investigated in a controlled study. Immediately following injury by an 8-sec 100 degrees C scalding, 25 mice were irradiated by a helium-neon laser at 0.05 J/cm2. A control group of the same size underwent identical treatment but received only sham irradiation. Serum lipid peroxide concentrations increased markedly in the control group at 0.5-4 h (P less than 0.0001, two sample t-test). In the laser treated group, the lipid peroxide concentrations remained relatively constant and were significantly depressed relative to the control group 4 h following burning (P less than 0.0001, two-sample t-test).

Acupressure-acupuncture antiemetic prophylaxis in children undergoing tonsillectomy.

BACKGROUND: Acupuncture or acupressure at the Nei-Guan (P.6) point on the wrist produces antiemetic effects in awake but not anesthetized patients. The authors studied whether a combined approach using preoperative acupressure and intra- and postoperative acupuncture can prevent emesis following tonsillectomy in children. METHODS: Patients 2-12 yr of age were randomly assigned to study or placebo groups. Two Acubands with (study) and two without (placebo) spherical beads were applied bilaterally on the P.6 points; non-bead- and bead-containing Acubands, respectively, were applied on the sham points. All Acubands were applied before any drug administration. After anesthetic induction, acupuncture needles were substituted for the beads and remained in situ until the next day. All points were covered with opaque tape to prevent study group identification. A uniform anesthetic technique was used; postoperative pain was managed initially with morphine and later with acetaminophen and codeine. Emesis, defined as retching or vomiting, was assessed postoperatively. Ondansetron was administered only after two emetic episodes at least 2 min apart. Droperidol was added if emesis persisted. RESULTS: One hundred patients were enrolled in the study. There were no differences in age, weight, follow-up duration, or perioperative opioid administration between groups. Retching occurred in 26% of the study patients and in 28% of the placebo patients; 51 and 55%, respectively, vomited; and 60 and 59%, respectively, did either. There were no significant differences between the groups. Redness occurred in 8.5% of acupuncture sites. CONCLUSION: Perioperative acupressure and acupuncture did not diminish emesis in children following tonsillectomy.     

Use of low-energy laser as adjunct treatment of alcohol addiction

Auricular acupuncture is a medical method that has been used in the treatment of alcohol addiction. In our study we decided to intensify this method by additional biostimulation of the whole organism. The aim of this study was the therapy of patients with alcohol dependence syndrome. Fifty-three alcoholics were treated with two types of laser stimulation in four sessions. Each session consisted of 20 consecutive daily helium-neon laser neck biostimulations and 10 auricular acupuncture treatments with argon laser (every 2nd day). The Beck Depression Inventory–Fast Screen (BDI-FS) was used to assess their frame of mind before the session and after 2 months of treatment. Moreover, -endorphin plasma concentration was estimated five times using the radioimmunoassay (RIA) method. Improvement in BDI-FS and increase in -endorphin level were observed. These results suggest that laser therapy can be useful as an adjunct treatment for alcoholism.

P6 acupressure may relieve nausea and vomiting after gynecological surgery: an effectiveness study in 410 women

PURPOSE: To investigate the effect of sensory stimulation of the P6 point on postoperative nausea and vomiting (PONV) after gynecological surgery in the everyday clinical setting (effectiveness study). METHODS: Four hundred and ten women undergoing general anesthesia for elective gynecological surgery were included in a prospective, consecutive, randomized, multicentre, placebo-controlled, double-blind clinical trial with a reference group. One group was given bilateral P6 acupressure (n = 135), a second group similar pressure on bilateral non-acupressure points (n = 139), and a third group (n = 136) served as reference group. Nausea (scale 0-6), vomiting, pain, and satisfaction with the treatment were recorded. Primary outcome was complete response, i.e., no nausea, vomiting or rescue medication for 24 hr. Results were analyzed by applying logistic regression with indicators of treatments, type of operation and risk score for PONV as explanatory variables. RESULTS: Complete response was more frequent in the P6 acupressure group than in the reference group (P = 0.0194) Conversely, the incidence of PONV was 46% in the reference group, 38% after pressure on a non-acupoint and 33% after P6 acupressure. The decrease from 46% to 33% was statistically significant. When considering vaginal cases separately, the decrease in PONV was from 36% to 20% (P = 0.0168). The corresponding decrease from 59% to 55% in the laparoscopic surgery group was not statistically significant. CONCLUSION: P6 acupressure is a non-invasive method that may have a place as prophylactic antiemetic therapy during gynecological surgery.     

Low power laser protects human erythrocytes In an In vitro model of artificial heart-lung machines

The protective effect of the low power helium-neon (He-Ne) laser against the damage of human erythrocytes in whole blood was examined in a perfusion model using an artificial heart-lung machine. Preserved human whole blood was diluted and perfused in 2 closed circuits with a double roller pump. The laser irradiated one of the circuits (laser group), and none the other (control group). In the laser group, erythrocyte deformability and erythrocyte adenosine triphosphate (ATP) levels were significantly higher, and free hemoglobin levels were significantly lower than those in the control group. Subsequent morphological findings by means of scanning electron microscope were consistent with these results. Low power He-Ne laser protected human erythrocytes in the preserved diluted whole blood from the damage caused by experimental artificial heart-lung machines. The clinical application of low power laser treatment for extracorporeal circulation is suggested.     

Effects of acupressure, manual acupuncture and Laserneedle acupuncture on EEG bispectral index and spectral edge frequency in healthy volunteers

BACKGROUND AND OBJECTIVE: The main purpose of this study was to investigate the effects of sensory (acupressure and acupuncture) and optical stimulation (Laserneedle acupuncture) on electroencephalographic bispectral index, spectral edge frequency and a verbal sedation score. METHODS: Twenty-five healthy volunteers (mean age +/- SD: 25.5 +/- 4.0yr) were investigated during the awake state. The acupuncture point Yintang and a placebo control point were stimulated. The study was performed as a randomized, controlled and partly blinded cross-over trial. RESULTS: Bispectral index and spectral edge frequency values both decreased significantly (P < 0.001) during acupressure on Yintang to values of 62.9 (minimum 35) +/- 13.9 bispectral index and to 13.3 (minimum 2.9) +/- 8.1 Hz (spectral edge frequency right) and 13.8 (minimum 2.7) +/- 7.3 Hz (spectral edge frequency left), respectively. Bispectral index was also significantly (P < 0.05) affected by Laserneedle acupuncture and acupressure on the control point but the changes were not clinically relevant, 95.4 +/- 4 and 94.2 +/- 4.8, respectively. All interventions significantly (Yintang: P < 0.001; control point: P < 0.012) reduced verbal sedation score. CONCLUSIONS: The study highlights the electroencephalographic similarities of acupressure induced sedation and general anaesthesia as assessed by bispectral index and spectral edge frequency.     

Open lung surgery with Nd-YAG Laser

We report on nineteen patients who successfully underwent open lung performance with a Nd-YAG laser in the period December 1987 to August 1988. Reasons for laser operations were lung metastases (twelve cases), lung fibrosis (five patients), one lung cyst and one tuberculoma. We used the Nd-YAG laser in non-contact mode, with focus hand-piece spot size of 1.5 mm, a continual 1064 nm wavelength and a power output 90 W. In these nineteen cases we performed 35 laser photoablations of lung tissue. All patients healed without any serious complications. The major advantage of Nd-YAG laser beam in open lung surgery is in the rapid sealing effect of small airways and of blood vessels up to 3 mm. The Nd-YAG laser seems to be very suitable for operations in lung periphery.     

China report. II. Laser medicine in the People's Republic of China

The application of lasers to medicine in the People's Republic of China allready has an history of more than fifteen years. Lasers are being used in various clinical departments such as ophthalomology, dermatology, otorhinolaryngology, surgery, obstetrics, gynecology, neurology, psychiatry, internal medicine, and acupuncture. A brief account of basic research and instrumentation is also presented. The academic activities of laser medicine in China are increasing repidly, and sugestions for the establishment of a Chinese Laser Medical Society have been proposed. The prospectives for laser medicine appear brilliant and promising.     

Effect of P-6 acupressure on prevention of nausea and vomiting after epidural morphine for post-Cesarean section pain relief

Background: Nausea and vomiting are important side effects following administration of epidural morphine for post-Cesarean section pain relief. Stimulation of the P-6 (Neiguan) acupoint is a traditional Chinese acupuncture modality used for antiemetic purpose; it has been found to be effective. The aim of this study was to evaluate the antiemetic effect of P-6 acupressure in parturients given epidural morphine for post-Cesarean section pain relief.
Method: In a randomized, double-blind and controlled trial, sixty parturients receiving epidural morphine for post-Cesarean section pain relief were investigated. Parturients were allocated to receive the acupressure bands or placebo bands on the P-6 acupoint bilaterally before the administration of spinal anesthesia and were observed over a 48-hour study period.
Results: The incidence of nausea and vomiting was significantly decreased from 43% and 27% in the control group, to 3% and 0% in the acupressure group, respectively ( P <0.05).
Conclusion: The results demonstrate that prophylactic use of acupressure bands bilaterally on the P-6 acupoint can significantly reduce incidence of nausea and vomiting after epidural morphine for post-Cesarean section pain relief.
