ABSTRACT
Background and Aims: Succinylcholine is the only available depolarizing neuromuscular blocker that has been widely used in the induction of anesthesia, and it is the drug of choice for rapid-sequence induction of anesthesia due to its rapid onset of effect and ultrashort duration of action owing to its rapid hydrolysis by acetyl-cholinesterase. Postoperative muscle pain (myalgia) and muscle stiffness are the most common side effects and are observed most frequently on the 1st postoperative day in ambulatory surgery. The use of succinylcholine in the induction of anesthesia and intubation in routine cases has been discouraged because of such adverse effects. However, because of its cost-effectiveness and easy availability, it is still used by some institutions routinely. This study aimed to study the efficacy of preoperative diclofenac along with atracurium precurarization in alleviating succinylcholine-induced myalgia. Materials and Methods: It is a double-blind randomized comparative study carried out in a tertiary care hospital. The study sample was 60 and divided into two equal groups. All data entered in MS-Excel Sheet and Wilcoxon signed-rank test were done for nonparametric data and one-way ANOVA for the parametric data. The normal distribution of the study sample was tested by the Shapiro - Wilk test. Results: The fasciculations in the test group were much less than in the control group with P < 0.00001. The results for the incidence of myalgia in the two groups were as follows: P value at 24 h was 0.00018 and at 48 h was 0.0028, respectively. Creatine kinase levels at preoperative and 24 h postoperative periods were 49.47 ± 7.24 in Group D, 53.30 ± 7.98 in Group B and 87.38 ± 15.16 in Group D, and 188.41 ± 33.27 in Group B, respectively. Conclusion: Succinylcholine-induced myalgia has a complex pathophysiology. However, the preemptive use of diclofenac in combination with precurarization can alleviate the incidence and severity of succinylcholine-induced myalgia. Therefore, its use may be considered in routine cases for induction of anesthesia for facilitating laryngoscopy and endotracheal intubation.
ABSTRACT
BACKGROUND: General anaesthesia (GA) is the conventional technique used for surgical treatment of breast lumps. However, various side effects and complications of GA, such as postoperative pain, nausea, vomiting, and increased hospital stay increase morbidity in patients. Regional anaesthesia using multiple injection paravertebral block is an ideal alternative to GA for breast surgeries. METHODS: Sixty female patients posted for unilateral breast surgery were randomly divided into two groups, Group P for paravertebral block and group G for GA, and compared on the basis of time taken for induction of anaesthesia, postoperative pain relief on basis of Visual Analogue Scale (VAS) score, postoperative nausea and vomiting (PONV) and duration of hospital stay. RESULTS: Duration of surgery in group P was 64.75±18.07 and 67.32±17.64 in group G respectively (P>0.05). Time for inducing anaesthesia was significantly longer in group P (17.15±3.92min) compared to group G (5.90±1.75min) with P<0.05. Significant difference (P<0.001) was observed in the mean duration of postoperative analgesia of group P (298.34±67.02min) and group G (107.68±27.28min). The VAS scores in immediate postoperative period and after two and four hours in the postoperative period were significantly higher in group G (P<0.05). The incidence of postoperative nausea and vomiting was significantly higher in group G (13 out of 30 patients) than group P (four out of 28 patients) with P<0.05. CONCLUSION: The efficacy and safety of paravertebral block for operative treatment of breast tumors, excellent analgesia in early postoperative period, requirement of significantly lesser amount of postoperative analgesics, decreased incidence of PONV and negligible complications along with early ambulation and hospital discharge makes it an afferent cost-effective block of choice for unilateral breast surgeries.
ABSTRACT
Background: Since 1898 when August Bier, introduced spinal analgesia, there is lot of advancement made in the technique. There are various approaches and techniques for subarachnoid block. Aim: The aim of this study is to compare median and paramedian approach for spinal anesthesia for cesarean delivery using Sprotte needle in terms of number of attempts, success rate, adverse effects, and complications. Materials and Methods: One hundred patients were randomly divided into two equal groups and underwent subarachnoid block in median and paramedical block for elective cesarean section. Results: There is no significant difference between the two groups. Mean with standard deviation in the number of attempts for subarachnoid block through media and paramedian approach is 1.18 ± 0.48 and 1.06 ± 0.24, respectively (P = 0.51). The incidence of postdural puncture headache (PDPH) and lower backache was insignificant in both the groups (P = 0.218 and 0.646, respectively). Conclusions: Paramedian approach should not be considered as a reserve technique for spinal anesthesia and can be used as popularly as the median approach.
