Role of Gabapentin in Traumatic Brain Injury: A Prospective Comparative Study

Background

Traumatic brain injury (TBI) is a major cause of mortality among young individuals, accounting for 65% of deaths in road traffic accidents. Paroxysmal sympathetic hyperactivity (PSH) is a common syndrome associated with TBI. This study represents the first prospective investigation aimed at assessing the impact of gabapentin on TBI patients, focusing on the prevention of secondary brain injury and brain edema while enhancing the Glasgow Coma Scale (GCS).

Materials and methods

The study was conducted from September 2019 to July 2021 after receiving ethical committee approval. It included adult ICU patients (≥18 years) with moderate and severe GCS. Patients below 18 years, death within 48 hours, non-consenting, pregnant females, and individuals allergic to gabapentin were excluded from the study. Patients were randomly allocated in two groups: study group received 300 mg of gabapentin orally twice daily and control group received multivitamin tablets twice daily. The treatment period spanned 2 weeks. Follow-up occurred in the ICU and continued for up to 3 months post-discharge, including telephonic conversations.

Results

About 60 patients were involved for analysis. Significant differences were found in GCS change from admission to discharge, Glasgow Outcome Scale (GOS) at 30 and 90 days, PSH episodes, and sedation bolus per day. Glasgow Coma Scale change was 53% in the study group compared with 25% in the control group (p = 0.009). Mortality was significantly lower in the study group. Glasgow Outcome Scale change between 30 and 90 days showed a 25% improvement in cases and no change in controls (p = 0.001).

Conclusion

This pioneering study underscores the potential of gabapentin in managing traumatic brain injuries.

Mesenteric Injury in Blunt Abdominal Trauma in Children: Is Early Surgical Intervention Need of the Hour?

Objective

There is an increasing trend of observational, nonsurgical management of abdominal injuries in children. We analyzed the feasibility and outcome of our management protocol in managing cases of the mesenteric injuries in blunt trauma abdomen in pediatric age group.

Methods

Single-center retrospective analysis of pediatric trauma case records from July 2018 to March 2020 was performed.

Results

Thirty-four cases of blunt abdominal trauma of whom 13 had mesenteric injuries were reviewed. The male-to-female ratio was 2.2:1, and the mean age was 9.11 ± 4.90 years. Mesentery of the small bowel was the most commonly injured segment and treatment consisted of repair of mesenteric tear, resection, and anastomosis with or without stoma formation.

Conclusions

Isolated mesenteric injury of all grades should be managed either with diagnostic laparoscopy or laparotomy irrespective of hemodynamic status.

Ultrasound-Guided Suprainguinal Fascia Iliaca Compartment Block for Postoperative Analgesia in Patients Undergoing Hip and Femur Surgeries: A Retrospective Analysis

Context:

Fractures of femur and hip surgeries pose a challenge because of excruciating pain. Fascia iliaca compartment block is an effective and easily learned procedure to decrease postoperative pain score and dosage of opioid. Many adjuvants are combined with local anesthetics to prolong the postoperative analgesia.

Aims:

The aim was to study duration of postoperative analgesia in terms of Numeric Rating Scale (NRS), number of times rescue analgesic used, any adverse effect, and patient satisfaction score.

Settings and Design:

Operation theatre of Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow.

Materials and Methods:

The present study was retrospective study with 203 patients evaluated. Based on the combination of the anesthesia and drugs, study patients were divided into six groups. Pain scores were assessed at 6 hourly intervals for 24 h.

Statistical Analysis Used:

Kruskal–Wallis H-test used to compare NRS as well as age and duration of anesthesia. Chi-square test/Fisher's exact test used to compare the proportions.

Results:

Postoperative analgesia was comparable and insignificant (P > 0.05) at 0, 6, 12 h in all six groups. Better postoperative analgesia was observed with dexmedetomidine and dexamethasone as adjuvant at 18 h, dexmedetomidine as adjuvant in comparison to dexamethasone as adjuvant at 24 h. Rescue analgesia in postoperative period was required maximum in plain bupivacaine. Satisfaction levels were good and excellent in dexmedetomidine and dexamethasone as adjuvant.

Conclusions:

Addition of dexmedetomidine to bupivacaine provides longer duration, good quality postoperative analgesia, reduced requirement for rescue analgesic, lesser postoperative nausea and vomiting, and better satisfaction levels.

Comparison of Dexmedetomidine and Midazolam for Sedation in Mechanically Ventilated Patients Guided by Bispectral Index and Sedation-Agitation Scale

Background:

Mechanical ventilation and sedation are inextricably linked components of critical care that represent, what we do for the patients during their vulnerable course in Intensive Care Unit (ICU).

Aims:

The aim of this study is to compare the efficacy and safety of midazolam and dexmedetomidine in patients on mechanical ventilator with the help of Bispectral Index (BIS) monitoring and correlation of BIS with Sedation-Agitation Scale (SAS).

Settings and Design:

Prospective, observational, and comparative study.

Materials and Methods:

In this study, recruited patients were allocated into two groups of 14 patients each. Group A and Group B patients received injection dexmedetomidine and injection Midazolam, respectively. Hemodynamic parameters, time of extubation, duration of mechanical ventilation, and mortality were compared between two groups.

Statistical Analysis:

Mean and the standard deviation were calculated. Test of analysis between two groups was performed using unpaired t-test. We applied correlation technique, that is, Pearson product-moment correlation coefficient (r) to assess the correlation between BIS and SAS. It varies from + 1–0 to −1.

Results:

Heart rate and blood pressure were more stable and less in Group A than Group B. Duration of mechanical ventilation was found extremely significant between Group A (77.86 ± 5.71 h) and Group B (95.64 ± 17.00 h) (P = 0.001). There was significant difference found in the time of extubation between Group A (21 ± 6.44 h) and Group B (30.4 ± 10.62 h) P = 0.008.

Conclusion:

It is concluded in this study that sedation with dexmedetomidine resulted in quick extubation and decreased the duration of mechanical ventilation in comparison to midazolam in ICU patients. There was found moderate to high correlation between BIS index and SAS.

Comparison of Enhancement of Analgesic Effect of Intrathecal Neostigmine by Intrathecal Clonidine and Transdermal Nitroglycerin Patch on Bupivacaine Spinal Anesthesia

Background

Relief of pain is very important goal intraoperatively and postoperatively. Neostigmine has been used successfully intrathecally with other agents such as clonidine and opioids for pain relief.

Aims

This study aims to compare and evaluate the efficacy and safety of combining intrathecal (IT) neostigmine with IT clonidine and transdermal nitroglycerin (tNTG) patch for the relief of pain in patients after surgery.

Settings and Design

This was a randomized, prospective, and comparative study.

Materials and Methods

In this study, recruited patients were randomly allocated into three groups. Groups I, II, and III received intrathecally 25 μg of neostigmine + 15 mg hyperbaric 0.5% bupivacaine, 25 μg of neostigmine + 25 μg clonidine + 15 mg hyperbaric 0.5% bupivacaine, and 25 μg of neostigmine + tNTG patch (3 cm × 5 cm, 5 mg/24 h) +15 mg hyperbaric 0.5% bupivacaine, respectively. Heart rate, mean arterial pressure, analgesic properties, and complications were assessed and compared among groups.

Statistical Analysis

Mean and standard deviation were calculated. Test of analysis between two groups was done by t-test and among three groups by ANOVA, then P value was calculated.

Results

Duration of analgesia was significantly longer in Group III in comparison to Group II (7.142 ± 1.81 vs. 4.408 ± 0.813 h) and was significantly longer in Group II in comparison to Group I (4.408 ± 0.813 vs. 2.583 ± 0.493 h). Analgesic requirement was significantly less in Group III in comparison to Group II (1.9 ± 0.76 vs. 2.5 ± 0.51) and was significantly less in Group II in comparison to Group I (2.5 ± 0.51 vs. 3.1 ± 0.48). Sedation score was found significantly high in Group II than other groups.

Conclusion

Both IT clonidine and tNTG patch with bupivacaine + neostigmine spinal anesthesia were found effective in pain control. Results were found better with tNTG patch.

Effect of intrathecal hyperbaric bupivacaine with small dose clonidine versus hyperbaric bupivacaine alone in lower abdominal surgeries: A comparative study

CONTEXT

The continued success of regional anesthetic techniques can be credited due to improved local anesthetic drugs, with lower toxicities and longer duration of action, but still many efforts are being done to increase the duration of the block and postoperative analgesia. Therefore, use of adjuvant drugs for anesthesia is intended to prolong analgesia and preventing deleterious clinical effects of local anesthetics.

AIMS

The present study is designed to evaluate effects of intrathecal hyperbaric bupivacaine versus hyperbaric bupivacaine with low dose clonidine on the onset and level of sensory and motor block, the intensity of motor blockade, and time of analgesia required in the postoperative period.

SETTINGS AND DESIGN

Study area were our operation theater and postanesthesia care unit of Department of Anesthesiology, this was a prospective, randomized, placebo-controlled, and double-blind study for a period of 1 year comprising of 60 patients.

MATERIALS AND METHODS

Patients were randomly allocated into two groups: Group 1 (S) (n = 30): Patients received intrathecal hyperbaric bupivacaine 12.5 mg with normal saline 0.5 ml and Group 2 (C) (n = 30): Patients received intrathecal hyperbaric bupivacaine 12.5 mg with 1 μg/kg clonidine (approximated to 0.5 ml with normal saline).

STATISTICAL ANALYSIS

Two groups were compared by Student's t-test, Chi-square test; ANOVA and significance of mean difference bet were done by Newman-Keuls test.

RESULTS AND CONCLUSION

Duration of analgesia was prolonged in Group C (363.07 ± 166.30 min) patients compared to Group S patients (226.95 ± 119 min) and they also required less top up analgesic in the postoperative period.
