Question
In an experiment to compare two different surgical procedures for hernia repair,† 89 children were assigned at random to one of the two surgical methods. The methods studied were laparoscopic repair and open repair. In laparoscopic repair, three small incisions are made and the surgeon works through these incisions with the aid of a small camera that is inserted through one of the incisions. In the open repair, a larger incision is used to open the abdomen. One of the response variables in this study was the amount of medication that was given after the surgery for the control of pain and nausea. The paper states "For postoperative pain, rescue fentanyl (1 µg/kg) and for nausea, ondansetron (0.1 mg/kg) were given as judged necessary by the attending nurse blinded to the operative approach." (a) Why do you think it was important that the nurse who administered the medications did not know which type of surgery was performed? O It is possible that the patients would have preconceived notions about their form of surgery and demand more medication for the laparoscopic repair. O It is possible that the nurses might have had preconceived notions about the two forms of surgery and the amounts of medication needed and could skew the results. O It is possible that nurses may have preconceived notions about the two forms of surgery and refuse to give medication to the open repair patients. O It is possible that the patients would have preconceived notions about their form of surgery and demand more medication for the open repair. O It is possible that nurses may have preconceived notions about the two forms of surgery and refuse to give medication to the laparoscopic repair patients. (b) Explain why it was not possible for this experiment to be double-blind. O Since the incisions made under the two procedures are the same, the patients and/or their parents would know which method had been used. O Since the incisions made under the two procedures are different, the patients and/or their parents would know which method had been used. O Since the two drugs used for the two procedures are different, the patients and/or their parents would know which method had been used. O Since the surgeon was different for the two procedures, the patients and/or their parents would know which method had been used. O Since the two procedures can't both be performed on the same patient, the patients and/or their parents would know which method had been used.
