The fibrosis involved in gluteus maximus causing limitation of flexion and adduction of the hip has become a recognized clinical entity since the first report by Fernandez de Valderrma in 1969. Its most constant and characteristic histologic feature was substitution of the fibrous tissue in the definitive etiology was unknown but presumed to be multiple intramuscular injections. Authors present three cases of the fibrosis involving gluteus maximus. In two cases Z-lengthening was performed on the thickened fibrous bands with good results.

Dislocation of the shoulder after intramuscular injection antibiotic(s) is rare and this conditon was limit described in literature. Our purposes were: (1) determining the clinical symptoms, X-ray and CT findings; and (2) determining the indications and the surgical technique and evaluation of the surgical result. Material and methods: 62 children (29 females, 33 males) aged from 4 to 16 years were included. Clinical and X- ray findings were analysed for anterosuperior subluxation or dislocation of humeral head. The patients were operated to release of origin or insretion of the mild Deltoid muscle or Z plasty of this one. Surgical procedures provided good result in 75.3 percent, fair in 24.7 percent and there were no infection or neuromuscular complication in these cases. Conclusions: This condition always resulted from repeated Deltoid intramuscular injection. The surgical treatment with resection of fibrous portions constantly gives relief of symptoms and provides good function.

Esfenvalerate is a kind of commonly used highly effective pyrethroid insecticide. It is common for people who are poisoned by contact or misuse, but rarely reported for people who are poisoned by intramuscular injection. This paper reports a case of intramuscular injection of esfenvalerate in the Department of Infection, West China Hospital of Sichuan University in November 2021. The patient was intramuscularly injected with about 20 ml of esfenvalerate, inducing the sense of swelling and tingling, degeneration and necrosis of striated muscle tissue at the injection site, also liver function damage and other manifestations. The patient was discharged from hospital after rehydration, accelerating poison metabolism, anti-infection, liver protection and local puncture.

BACKGROUND: Although used for obtund pain, bupivacaine may itself initially produce pain on injection. This study was designed to evaluate the effect of diluting bupivacaine with normal saline, lactated Ringer's solution, 5% dextrous in water and distilled water on perception of pain associated with intramuscular injection. METHODS: Twenty-five healthy volunteers were involved in this study. Each subject received 4 injections in random order: 0.25% bupivacaine in normal saline, lactated Ringer's solution, 5% dextrous in water and distilled water. Both upper trapezius muscles were used for the intramuscular injection site. Needle size (25-gauge), injection depth (1.5-2 cm), injection volume (2.5 ml), administration speed (0.5 ml/sec), and temperature (room) were controlled for each of the four injections. The intensity of pain was rated on a 0 to 10 visual analogue scale (VAS) score at the point of needle insertion and injecting solutions. RESULTS: There was no statistical difference among each solution in VAS score. However, the VAS scores of drug administration were higher than those of needle insertion in all diluting solutions (P<0.05). CONCLUSIONS: There was no difference in the intensity of pain of an intramuscular injection of bupivacaine between four different kinds of solutions. However, it might be suggested that more effort and investigation will be needed to reduce pain with an intramuscular injection.

Although anaphylactic shock during the perioperative period is rare, it can be lethal due to severe cardiovascular and respiratory collapse. Midazolam is generally used as premedication for relieving anxiety about the operation, and the danger of anaphylactic shock after intramuscular injection is not widely recognized. We report the first case of anaphylactic shock occurring during the perioperative period after intramuscular injection of midazolam. Since anaphylactic shock after intramuscular injection can be of slow onset, the operation should be delayed if an anaphylactic reaction is suspected, even if the symptoms are limited. In addition, anesthesiologists should be prepared for the occurrence of anaphylaxis at any time in the perioperative period.

PURPOSE: The evaluation of pain in neonates is difficult due to their limited means of communication. The aim of this study was to determine whether the behavioral reactions of facial action and cry provoked by an invasive pain-induced procedure could be discriminated from the reactions to a noninvasive pain-induced procedure in normal full-term neonates. METHODS: Thirty-six healthy full-term neonates received three pain-induced procedures in counterbalanced order:intramuscular injection, tactile stimulus, and rubbing thigh with alcohol. The facial actions to the pain-induced procedures were measured and analysed by Neonatal Facial Action Coding System (NFACS) and the cry measures were analysed by the speech analysis after recording. RESULTS: 1) A cluster of facial actions comprised of brow bulging, eye squeezing, deepening of nasolabial furrow and open mouth was associated most frequently with the invasive procedure and the total facial action was the highest score in intramuscular injection. 2) Acoustic analysis of cry showed the shortest latency to the first cry and the lonegst duration of the first cry in intramuscular injection. 3) Two variables, total facial action and duration of the first cry, were most statistically significant in discriminating the invasive pain-induced procedure from the noninvasve pain-induced procedure. CONCLUSION: The facial actions and cry responses to the invasive pain-induced procedure were significantly different from the responses to the noninvasive pain-induced procedure in healthy full-term neonates.

PURPOSE: We evaluates if the administration of tamsulosin increases the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the patients with upper ureteral stones and if this decreased the use of analgesic drugs after the procedure. MATERIALS AND METHODS: A total of 45 patients with stones 6-12mm in size that were located in the upper ureter were enrolled in the study. The patients were randomly divided into two groups. Group 1 (n=23) received 3 times a day oral treatment of 20mg caroverine (a spasmolytic drug). Group 2 (n=22) received one time a day oral therapy of 0.2mg tamsulosin. All the patients received oral treatment for 14 days. Both groups of patients were allowed to use 30mg ketorolac trimethamine intramuscular injections on demand. The endpoint of the study was the stone expulsion rate, the use of analgesics and the drug adverse effects during treatment. RESULTS: The average stone size was 7.9+/-2.79mm for group 1 and 8.2+/-3.14mm for group 2. No statistical difference between the two groups was found for the stone size, age and gender distribution. The expulsion rate was significantly higher in group 2 (90.9%) compared with group 1 (65.2%) (p=0.038). The average number of pain control injections was 0.78 for group 1 and 0.23 for group 2, and there was a statistically significant difference between the two groups (p=0.042). CONCLUSIONS: The use of tamsulosin proved to be effective and safe, as demonstrated by the increased stone expulsion rate and the lesser need for pain control than that when using just a spasmolytic drug for ESWL of upper ureter stones.

BACKGROUND: The stress of operation inhibits bowel motility. The blockade of efferent sympathetic nerve is helpful to recovery of bowel motility. So we tried to examine that the extent of sympathetic blockade by alterations of bupivacaine infusion rate affected the recovery of bowel motility. METHODS: Group 1 (N = 25) received postoperative meperidine intramuscular injection on demand as a control group, group 2 (N = 25) received postoperative epidural 0.125% bupivacaine 100 ml plus morphine 10mg by infusion pump, 1 ml/hour, for 4days, group 3 (N = 25) received 0.125% bupivacaine 400 ml plus morphine 10mg by infusion pump, 4 ml/hour, for 4days. The Group 2 and 3 received additional morphine 2mg in 0.2% bupivacaine 10 ml epidurally as a single bolus when the peritoneum was closed. The time interval from termination of operation to the first passage of flatus was estimated. RESULTS: In group 1, bowel motility was regained at 92+/-23 hours, group 2 ; 90+/-19 hours and group 3 ; 91+/-19 hours. All values are not significantly different among the groups (p>0.05). CONCLUSIONS: The alteration of epidural bupivacaine and morphine infusion rate did not affect the recovery of postoperative bowel motility.
