Introduction: Nausea  and  vomiting  is  a  common  manifestation  in  anatomic  as  and  Functional  disorders, and  these  are  current  complications after  general  anesthesia  and  are  unpleasant  and  with  secondary  complications. Nausea  and  vomiting  are  the  most  common  complications  after  general  abesthesia.
Materials  and  Methods: In  this  study  we  compared  three  methods  which  one  of  them  is  acupressure  (non  invasive  and  non  medical  and  is  one  of  subtype  of  acupuncture)  with  other  methods  consisting  of  IV  metoclopramide  and  placebo.  This  controlled  study  was  done  in  teaching  Vali-Asr  hospital. Total  number  of  patients  was  420, type  of  sampling  was  random. Type  of  operation  was  laparotomy  and  all  of  them  had  general  anesthesia. We  divided  them  in  three  equal  groups  (acupressure  group, metoclopramide  group, and  placebo  group). In  this  study  we  used  from  history  and  examination  and  we  finished  puzzles  and  we  use  from  statistician.
Results:  we  concluded  that  there  is  no  valuable  difference  between  metoclopramide  and  acupressure  group ( with  considering  odds-Ratio  and  0.6).  we  resulted  that  with  using  from  acupressure  and  IV  metoclopramide  there  will  be  lesser  nausea  and  vomiting  when  comparing  these  two  groups  with  placebo.
Conclusion: We  compared  these  data  we  find  that  acupressure  is  a  suggestive  and  valuable  method  and  also  noninvasive  and  inexpensive  and  also  effective  method  in preventing  post   operative  nausea  and  vomiting.

Introduction: One of the most important skills which should be learned and performed by physicians and nurses is the correct method of intubation. Therefore, more attention should be given to such trainings. The main purpose of the recent study is manufacturing and utilization of a detector device for correct intubation which can be used by inexpert staff who are not members of anesthesia team.
Materials and Methods: In a quasi experimental study a detector device was manufactured and utilized for correct intubation. In this research 400 patients undergone surgery, had been chosen for testing the device. Their ages varied from 5-75 years old and they had no chronic obstructive pulmonary disease (COPD), asthma and heart disease. These patients have been generally anesthetized. In all patients the tracheal tube has been placed in esophagus and then immediately in trachea, using the device. The sensitivity of device was evaluated. During the procedure patients, oxygenation was not disturbed.
Results: All 400 intubations were performed succesfuly using the device. In this study using air flow out of lungs, intubation was done successfuly. So the devices, sensitivity was 100%. By a professional the mean time for intubation using this device was 5 seconds, and it,s price was 1000 Rials.
Conclusion: Regarding the results, it seems the device is useful in emergencies and facilitates intubation. This device is cheap and portable and seems to be more useful than other reported devices in determining correctiveness of intratracheal intubation.
