ABSTRACT
Background and Aims: Caudal block is among the most widely administered regional anesthesia in pediatric patients. The clinical signs and objective assessments are not fast and reliable enough to provide a good feedback. Perfusion index (PI) is considered as a sensitive marker to assess the efficacy of caudal block. We aim to assess PI as an indicator for success of caudal block in pediatric patients. Material and Methods: Sixty pediatric patients scheduled for elective surgery of lower abdomen and below were included. Patients were randomly allocated into two groups (n = 30): Group 1 received caudal block after general anesthesia and Group 2 only received general anesthesia. PI, heart rate, mean arterial pressure, and anal sphincter tone (AST) were recorded at 5, 10, 15, and 20 min following induction of anesthesia. Results: A persistent increase in the PI value was observed in Group 1 starting from 5 min till 20 min, as compared to Group 2, at all the time intervals. When mean PI was statistically compared between both the groups, it was found to be highly significant (P = 0.001). Group 1 patients have progressive laxity of AST which was found to be significantly different from Group 2 (P < 0.001). Conclusion: We have found that both PI and AST are good indicators for assessing success of caudal block onset in pediatric patients but AST took slightly longer time (~20 mins). Therefore, we conclude that PI is simple, economical, and noninvasive monitor that predicts the caudal onset much earlier than AST.
ABSTRACT
OBJECTIVE: The surgical repair of hypospadias is done in two stages in a select group of patients with severe anomaly. The first stage (I) procedure consists of correction of penile shaft curvature and second stage (II) repair involves the creation of a neourethra. This neourethra needs a cover of an intermediate layer in order to have good functional and cosmetic results. Among the various local flaps, tunica vaginalis flap is a good option for the use as an intermediate layer. METHODS: We have managed 22 patients of chordee with hypospadias by staged repair. In Stage I, chordee correction was done by dividing the urethral plate and covering the penile shaft with dorsal prepucial flaps. In Stage II, a neourethra was created and covered with tunica vaginalis flap either through the same incision (14/22) or via a subcutaneous tunnel (8/22). An indwelling catheter was kept for 10 to 12 days. RESULTS: Eighteen (81.8%) patients had successful functional and cosmetic repair. Two patients (9.1%) had urethrocutaneous fistula of which one healed on subsequent dilatation while the other one (4.5%) needed repair. Overall fistula formation rate was 4.5%. In two patients, the external urinary meatus could be made upto subglanular or coronal level. CONCLUSION: Staged repair of chordee with hypospadias is valuable in selected group of patients and tunica vaginalis flap is an excellent intermediate layer to cover the neourethra. However preoperative counseling is particularly essential in patients where the external urinary meatus can be created at coronal or subglanular level.
ABSTRACT
Splenic abscess is uncommon in paediatric age group. It usually occurs in conditions of disseminated infective focus. Conventional treatment of abscess is incision and drainage, although splenectomy or splenic conservation is alternative. In this report, we are presenting case summaries of three patients suffering from splenic abscess. A retrospective review of three children was managed for splenic abscess in our institution.All three patients presented with pyrexia, weight loss, and recurrent abdominal pain for more than six weeks. Human immunodeficiency virus (HIV) antibody detection test (ELISA) was nonreactive in all of them. The first patient was managed by splenectomy because of multiple splenic abscesses involving the entire spleen; the second one had exploratory laparotomy and drainage of splenic abscess with preservation of the spleen; and the third patient had successful ultrasonic guided aspiration of abscess. The follow-up ultrasonography done after three and six months in two patients, with splenic conservation, did not reveal any recurrence of abscess. In children with splenic abscess, ultrasound guided aspiration of abscess should be the first line of treatment, when this fails either because of multiple abscesses or dense adhesions around the spleen then splenectomy or open drainage may become necessary.
