This action was commenced by plaintiffs, who are husband and wife, for the purpose of recovering damages for injuries to Mrs. Key resulting from the negligence of ap *700 pellant, a physician and surgeon, in performing a Caesarean operation upon Mrs. Key. Several defendants were named in the complaint but the action proceeded to judgment against appellant alone. The appeal is from a judgment in favor of plaintiffs.
Plaintiffs were members of the Better Health Foundation, a group health organization, which in consideration of monthly dues agreed to furnish them with necessary surgical and obstetrical services in connection with the anticipated birth of Mrs. Key’s child. Plaintiffs were referred by the Foundation to a clinic and hospital headed by appellant for prenatal and obstetrical services. On August 31, 1938, after labor had started, Mrs. Key went to the hospital, where she was examined by appellant. Because of complications resulting from her poor physical condition appellant decided that Mrs. Key would be unable to have a normal delivery and that a Caesarean operation was necessary. Appellant commenced the operation and as it progressed it became apparent that the patient was a poor surgical or anaesthetic risk and that it was essential that the operation be completed in the shortest possible time. Appellant therefore completed the operation as rapidly as possible. In the course of the operation many laparotomy sponges were used for the. purpose of walling off various organs of the patient’s body from the operating field. The nurses assisting him made two sponge counts at his request and announced them to be correct, thus indicating to appellant that all sponges used in the operation had been removed from the patient’s body. This conclusion was found to be erroneous when, approximately five weeks later, it was discovered that one of the sponges used in the operation had not been removed from Mrs. Key’s body and that as a result she had suffered certain injuries. This interring of a laparotomy sponge in Mrs. Key’s abdomen constitutes the alleged negligent act out of which the present action arose.
William Caldwell was originally named as a defendant and an alleged partner of appellant but prior to trial the action was dismissed as to him with prejudice. Caldwell, who had filed a cross-complaint against plaintiffs based upon their failure to pay dues to the Foundation, dismissed his cross-complaint with prejudice. Following the dismissal
of
the action as to Caldwell appellant made a motion for permis
*701
sion to file a supplemental defense in the nature of a
retraxit,
which was denied. During the course of the trial the motion for leave to interpose the supplemental defense was renewed and again denied. It is now contended by appellant that the court abused its discretion in refusing to permit him to interpose such defense. In support of his position it is urged by appellant that the dismissal with prejudice as to defendant Caldwell amounted to a
retraxit,
the result of which was to release appellant as a joint tort-feasor from further liability to plaintiffs. It is settled that before a voluntary dismissal as to one defendant will operate as a release of a co-defendant it must appear that the defendants are joint tortfeasors and that plaintiff has received some satisfaction for such dismissal.
(Shea
v.
City of San Bernardino,
7 Cal. (2d) 688 [
Appellant’s contention cannot be sustained for the reason that there is no evidence that appellant and Caldwell were joint tort-feasors and for the further reason that there is no evidence that plaintiffs received any satisfaction for the dismissal of the action. Although it is true that appellant and defendant Caldwell were alleged to be partners this allegation was denied by appellant in his answer. In connection with his claim of
retraxit
appellant offered to prove that defendant Caldwell, who operated the Better Health Foundation, had an agreement with appellant under which the latter was obligated to furnish obstetrical and surgical services to members of the Foundation. In making such offer of proof the attorney for appellant stated: “I will say as a prelude that I do not understand that relationship to be either a partnership nor a joint venture. ’ ’ Caldwell was not a physician and did not participate in any manner in the actual operation which was performed by appellant. The record is silent as to any master and servant relationship between Caldwell and appellant, so that the doctrine of
respondeat superior
is not applicable. The situation thus presented falls far short of showing any such concert of action as would be required to render appellant and Caldwell liable as joint tort-feasors.
(Weinberg Co.
v.
Bilby,
*702
The record fails even to suggest that plaintiffs received any satisfaction for the dismissal. Clearly, unless some satisfaction has been received there can be no
retraxit. (Bee
v.
Cooper,
It is contended by appellant that there is no evidence to support the finding that he was negligent. It is conceded by both parties that the doctrine of
res ipsa loquitur,
“where the thing is shown to be under the management of the defendant or his servants and the accident is such as in the ordinary course of things does not happen if those who have the management use proper care, it affords reasonable evidence, in the absence of explanation by the defendant, that the accident arose from want of proper care”, is applicable to the present case.
(Ales
v.
Ryan,
8 Cal. (2d) 82, 95 [
Appellant’s argument is that since there was no evidence to establish a departure from approved medical practice and, on the contrary, it was established by his own testimony that he did follow the usual and ordinary practice in performing this operation the inference of negligence raised by the doctrine of res ipsa loquitur was definitely rebutted. It is further urged that what is or is not proper medical practice can only be established by expert testimony which, when not conflicting, is conclusive. Although appellant relies upon rules which are applicable in many cases of malpractice, it must be held that the finding of the trial court that defendant was negligent, in view of the facts of the present case, is supported by the evidence. It has been held that “ . . . the failure to remove a sponge from the abdomen of a patient is negligence of the ordinary type and that it does not involve knowledge of materia medica or surgery but that it belongs *704 to that class of mental lapses which frequently occur in the usual routine of business and commerce, and in the multitude of commonplace affairs which come within the group of ordinary actionable negligence. . . . General negligence cannot be excused on the ground that others in the same locality practice the same kind of negligence.” (Ales v. Ryan, supra.) Appellant’s testimony that he followed the usual and ordinary practice in performing the operation does not compel a finding that the inference of negligence arising from the fact that he failed to remove one of the sponges was rebutted. The question whether such inference has been rebutted is ordinarily for the determination of the trial court.
The question before us for determination is whether the record discloses support for the finding that appellant did not use reasonable care and skill. Such finding is not rendered ineffective by proof that appellant followed the practice and methods ordinarily used by surgeons in the same locality. In
Ales
v.
Ryan, supra,
at page 103, the court quotes with approval from
Davis
v.
Kerr,
Appellant rests his case entirely upon the testimony that in completing the operation as speedily as possible and in relying upon the sponge count by the nurses he was following the usual and ordinary practice of other physicians in the same locality. It has been held that a surgeon cannot relieve himself of liability by proof of a custom or practice among surgeons requiring the nurses to count the sponges used in an operation. In Ales v. Ryan, supra, p. 105, the court quotes with approval the rule set forth in 21 Ruling Case Law, 338, to the effect that “surgeons cannot relieve themselves from liability for injury to a patient caused by leaving sponges in a wound after operation, by the adoption of a rule requiring the attendant nurse to count the sponges used and removed, and relying on that rule as conclusive that sponges have been accounted for”. Since the operation was performed under the immediate supervision and direction of appellant he was charged with the responsibility of determining that all sponges were removed from the operating field before the incision was closed.
The judgment is affirmed.
Moore, P. J., and MeComb, J., concurred.
A petition for a rehearing of this cause was denied by the District Court of Appeal on July 23, 1940, and an application *706 by appellant to have the cause heard in the Supreme Court, after judgment in the District Court of Appeal, was denied by the Supreme Court on August 26, 1940. Edmonds, J., and Houser, J., voted for a hearing.
