Anterior midline or medial parapatellar incision for arthroplasty of the knee. A comparative study.

Early mobilisation after arthroplasty of the knee sometimes results in wound breakdown. The two commonly used incisions, the anterior midline and the medial parapatellar incisions, were compared in order to determine which had the best potential for wound healing. Study of the cleavage lines around the knee demonstrated that the medial parapatellar incision lies parallel to the lines, whilst the anterior midline incision lies perpendicular to them. In addition, the medial parapatellar wound was found to be subjected to significantly less tension during flexion; after arthroplasty it can be expected to heal faster and to be less liable to disruption during early mobilisation.

Caudal block for postoperative analgesia in children.

A clinical trial was performed to compare the effects of intramuscular dihydrocodeine with caudal bupivacaine on postoperative pain and recovery in 181 children who had undergone either circumcision, inguinal herniotomy or orchidopexy performed under general anaesthesia. Linear analogues were used in assess level of consciousness and apparent pain. Recovery of consciousness was slower after caudal analgesia. For 90 minutes following circumcision there was significantly less pain and caudal analgesia, but better pain relief could not be demonstrated following inguinal herniotomy and orchidopexy.

Glycopyrrolate in children.

The effects of glycopyrrolate 10 microgram kg-1 i.v. given at induction of anaesthesia were compared with those of atropine 20 microgram kg-1 i.v. given at induction and oral atropine 30 microgram kg-1 given 90 min before operation. Antisialagogue effect, changes in axillary temperature, heart rate, frequency of cardiac arrhythmia and postoperative restlessness were determined. Patients who had received oral atropine had more pharyngeal secretions, a lower heart rate and a greater frequency of cardiac arrhythmia than when either atropine or glycopyrrolate was given i.v. Secretions were significantly less during operation when i.v. glycopyrrolate was used.

Morbidity after outpatient anaesthesia. A comparison of two techniques of endotracheal anaesthesia for dental surgery.

A comparison was made of two anaesthetic techniques for outpatient dental surgery; the basis for comparison was symptomatic morbidity. One group of patients was managed with spontaneous breathing of nitrous oxide, oxygen and halothane; the other was ventilated mechanically, and received fentanyl and alcuronium. The latter anaesthetic was associated with a significantly higher incidence of morbidity on the day of operation, but not subsequently. The incidence of dysrhythmias was not significantly different. The comfort and safety of patients are discussed in relation to the choice of anaesthetic.

Metallized plastic sheeting in the prevention of hypothermia during neurosurgery.

Metallized plastic sheeting (m.p.s.) was found to be ineffective in the prevention of hypothermia in adult patients studied during neurosurgical operations. Twenty patients were wrapped in m.p.s. and 22 patients acted as controls. Mean oesophageal temperature in the m.p.s. group decreased from 36.2 degrees C to 35.4 degrees C after 3 h (control 36.5 degrees C to 35.4 degrees C). It was concluded that active warming systems are needed to maintain normothermia in patients undergoing neurosurgical operations.
