title: Combination of transcutaneous electrical nerve stimulation and ondansetron in preventing cisplatin-induced emesis.
abstract: OBJECTIVE
  To find out whether the combination of transcutaneous electrical nerve stimulation (TENS) and ondansetron had an increased antiemetic effect.
  
  
  METHODS
  Fourteen testis and 11 bladder cancer patients were scheduled for 4 cycles of bleomycin-etoposide-cisplatin (BEP) or methotrexate-vinblastine-etoposide-cisplatin (MVEC) combination chemotherapy, respectively. At each cycle the whole cisplatin dose was given in 1 day that is 100 mg/m(2)/day in the BEP and 70 mg/m(2)/day in the MVEC protocols. Ondansetron was given at a dose of 12 mg/day and TENS was applied by commercially available 'Relief Band'(Maven Labs, Inc., Citrus Heights, Calif., USA). The first 3 cycles of each case were blindly randomized to one of the following regimens; TENS vs. ondansetron vs. a combination of both. The regimens were applied during the administration of cisplatin and the patients were asked to report their nausea according to a scale between 0 to 10. Also for each regimen the number of emetic attacks experienced during the administration of cisplatin was recorded by the same observer. Then the scores of each regimen were compared.
  
  
  RESULTS
  The mean nausea scores for regimens TENS, ondansetron and TENS + ondansetron were found to be 5.12 +/- 2.54, 3.0 +/- 1.71 and 0.8 +/- 0.96, respectively. Ondansetron was better than TENS in preventing nausea (p = 0.000). However the combination of TENS and ondansetron resulted in a significant decrease in nausea scores when compared to TENS alone (p = 0.000) or ondansetron alone (p = 0.000). The mean number of emetic attacks for the TENS, ondansetron and TENS + ondansetron regimens were 3.16 +/- 1.84, 1.64 +/- 1.44 and 0.56 +/- 0.82, respectively. A statistically significant difference was present between the number of emetic attacks observed with the TENS + ondansetron combination and TENS alone (p = 0.000) or ondansetron alone (p = 0.001). Ondansetron was again better than TENS in preventing emetic attacks (p = 0.001).
  
  
  CONCLUSIONS
  The use of TENS as an adjunct to ondansetron therapy has provided significant benefit in preventing nausea and emetic attacks caused by cisplatin.
