[ comparison of the efficacy of intra-articular injection of morphine with marcaine in patients to relief the pain associated with knee arthroscopy]

Knee arthroscopy is an approved technique for the diagnosis and treatment of intra-articular lesions. Moderate to severe pain is experienced after surgery; thus, relieving pain post arthroscopy, will help patients in performing their daily activities as soon as possible. Many studies have been performed for reducing pain after arthroscopy. The aim of this study is to compare the efficacy of intra-articular injection of morphine with marcaine in patients for pain relief after arthroscopy. 30 patients were considered for arthroscopic surgery, due to the tearing of the menisci. In this simple non-probability trial, patients were divided in two groups. The first group received 7cc intra-articular marcaine at 0.5% and the second group received 10mg of intra-articular morphine after the arthroscopy. The response was measured by VAS in hours 6, 12, 18, 24 postoperatively and by flexion, extension and walking. The results showed that there was no significant statistical difference between the two groups, except in hour 6 after surgery, indicating marcaine is more effective than morphine. There were no side effects experienced within the two groups. Age, gender, height and weight also had no effect in reducing the pain in patients. Intra-articular Injection of marcaine is more effective than morphine six hours after surgery; however, there are no differences between them after that time frame. More research is needed in order to reduce pain after arthroscopy

effect of starting treatment in the prevalence of scaphoid nonunion

Scaphoid fractures are the most common wrist fractures; immobilization of wrist by plaster of Paris is the treatment of choice in persisting fractures of the middle and terminal part of the scaphoid. Many factors are effective on nonunion of scaphoid bone. The purpose of this study was to determine the relation between delay in starting treatment [1 to 3 weeks] with prevalence rate of fracture nonunion. In this study, the result of union in 57 patients with middle part fracture of the scaphoid and 1 to 3 weeks delay in treatment was compared with 60 patients as control who referred for treatment on the first day of fracture. Out of 57 cases under study, in 8 there was nonunion and in the control group, only 2 patients had nonunion, which indicated delay in treatment is significantly effective on nonnunion of scaphoid fractures [p<0.05]. It is recommended that in case of feeling pain and sensitivity on the snuffbox after trauma to wrist even when there is no evidence of fracture line in radiography be considered scaphoid fracture and treatment with plastering be undertaken and delay in starting treatment due to the increase in prevalence rate of scaphoid nonunion
