This is an action for malpractice, to recover damages for injuries to the plaintiff’s wrist claimed to have been caused by the negligent and unskilful conduct of the defendant in applying diathermic treatment. Upon the trial the jury returned a defendant’s verdict, which the plaintiff moved to set aside. The court denied the motion and the plaintiff has appealed from the judgment rendered on the verdict. Of the many questions raised in his assignments of error, only two have been argued orally and in his brief. The others must, therefore, be treated as abandoned.
Freund
v.
Burns,
The plaintiff offered evidence to prove the following facts: The defendant is a physician engaged in the general practice of medicine in Naugatuck. On August 28, 1949, the plaintiff sprained his right *379 wrist and on the next day went to the defendant about the injury. After examining the wrist, the defendant first massaged it and then applied an ace bandage. The plaintiff returned to the defendant’s office on September 3, 1949. On that occasion, the defendant decided to apply special treatment to the wrist. For that purpose he took the plaintiff to a room located in the rear of the large house which the defendant used both as his offices and as his home. In this room, which was about fifteen feet from his private office, was a diathermy machine. After having his patient sit down on a stool, the defendant put around the plaintiff’s wrist and forearm rubber cuffs which were connected by cables to the machine. The defendant did not apply any padding or gauze to the plaintiff’s skin where it was in contact with the cuffs. After first turning some dials on the machine, the defendant switched it on. He then left the room without giving the plaintiff any instructions as to the cuffs or the machine.
About fifteen minutes later, the plaintiff, feeling a burning sensation in his wrist, called loudly for the defendant but received no response. The plaintiff thereafter continued to call but it was not until another fifteen minutes had passed that the defendant came to the treatment room and turned the machine off. Upon removal of the cuffs the plaintiff’s wrist was found to be reddened. Subsequently the wrist became blistered, and although treated by the defendant until February, 1950, it failed to heal properly. The burn has left a permanent scar which may require surgery, and the strength of the hand has lessened. It will not be necessary to mention the defendant’s claims of proof other than to observe that in the vital instances they were exactly contrary to those of the plaintiff.
*380 The court charged the jury that while a physician must exercise reasonable care, skill and diligence, “the law does not exact from him the utmost degree of care and skill obtainable or known to the profession.” It is this quoted statement which the plaintiff attacks. His point is that the statement was erroneous since it improperly limited the degree of care required of the defendant by law. More particularly, the plaintiff asserts that reasonable care may, under certain circumstances, demand a very high degree of care if one is to escape liability.
To support his claim the plaintiff cites
Geoghegan
v.
G. Fox & Co.,
Before making the statement under attack, the court had charged that the duty of the defendant in his capacity as a physician was to exercise reasonable care, skill and diligence in treating the plaintiff as a patient, and that this duty was met if the defendant exercised that degree of skill and care which physicians in the same general neighborhood and in the same general line of practice ordinarily
*381
have and exercise in like cases. This instruction conformed to our law.
Sheridan
v.
Quarrier,
The other assignment of error pressed by the plaintiff deals with the court’s refusal to charge the jury in a particular requested by him. The request ran to the effect that if the diathermy machine was equipped with an alarm signal which could be set to give the patient warning of the end of the treatment and if “the exercise of reasonable care, skill and diligence required, that such alarm signal should be set and [if] the defendant failed to set said alarm signal, then you may find the defendant liable for malpractice.” In the ordinary action for negligence, the jury require no evidence as to the degree of care a defendant should use under the circumstances. This does not apply, however, to an action for malpractice. Since the members of the jury are laymen,
*382
they cannot be expected to know the requirements for proper medical treatment in the usual case. The evidence of experts is ordinarily necessary.
Haliburton
v.
General Hospital Society,
The plaintiff’s attempt to utilize the assignment of error under discussion as presenting an evidential question concerning the credibility of the defendant is not possible under the record.
There is no error.
In this opinion the other judges concurred.
