Mortality And Prognostic Factors In Patients Operated For Acute Epidural Hematoma.

Background: Epidural hematoma is one of the most common surgical emergencies encountered in neurosurgery. This study was conducted to determine the mortality and prognostic factors in patients operated for traumatic intracranial epidural hematoma in a resource-constrained setting from a developing country. Methods: This retrospective study was conducted in the Department of Neurosurgery at Ayub Teaching Hospital Abbottabad from 1st January 2019 to 31st Dec 2021. Inclusion and exclusion criteria were created. The medical record of 116 patients admitted and operated on for traumatic extradural hematoma was retrospectively reviewed. Information was recorded using a standardized structured questionnaire. The outcome was measured in terms of the Glasgow coma outcome score. Results: Out of 116 patients, 93 were male and 23 were female.19 (16.4%) patients were in the age range 0-5 years, 42 (36.2%) were in the age range 6-15, 35(31.0%) were in the age range 16-30, 11 (9.5%) were in the age range 31-45 years, 7 (6.0%) were in the age range 46-60 years while only one patient included in this study was above 60 years. Overall mortality was 4.3%. Mortality was higher in females and in those aged less than 5 years (3.4%). 4 out of 16 patients died with GCS less than 8, while none of the patients died when GCS was above 12. Mortality was significantly higher in the presence of associated lesions (4.4% vs. 0%) and anisocoria (2.6% vs.1.7%). Patients who operated within 6 hours of trauma resulted in better outcomes with a mortality rate of 0.0% and functional recovery of 57.8 % while for those who operated after 6 hours, mortality was significantly higher (4.3%) and functional recovery was significantly low (15.5%). Conclusion: Good surgical outcomes can be achieved with early operative intervention if indicated. Female gender, low preoperative GCS score, presence of pupillary dilatation, presence of associated lesions, delayed surgical intervention and age less than 5 years are significant predictors for poor outcomes.

Efficacy Of PanbioTM Covid-19 Ag Rapid Test In Sars-Cov-2 Detection: Comparison With RT-PCR Test.

Background: Evidence on performance of Rapid Antigen Detection Tests to recognize SARS-CoV-2 symptomatic patients in our context is limited. This study was aimed to evaluate Panbio™ COVID-19 Ag Rapid Test Device (Abbott Diagnostics, Jena, Germany) in identifying SARS-CoV-2 infection in comparison with RT-PCR test. Methods: This cross-sectional validation study was carried out at Margalla Hospital, Taxila from October, 2020 to March, 2021. Three hundred and eighty-two participants of both gender and all ages, symptomatic for 3-4 days were included in this study. For each participant, two nasopharyngeal swabs were collected by trained lab technicians according to SOPs, one for Rapid Antigen Test and other for RT-PCR.Covid-19 antibodies were checked 4-6 weeks after symptoms among 77 randomly selected participants to further evaluate the performance of Rapid Antigen Test. Data was analyzed using SPSS-26. Results: The mean age of the participants was 43.1 years (SD=15.9). More than half of participants were males (n=213%=55.8) and 169 (44.2%) were females. Sensitivity of Rapid Antigen Test was calculated to be 94.3%, whereas the specificity was 39.7%. Out of 34 RT-PCR negatives that were initially detected positive on Rapid Antigen Test, 33 demonstrated presence of COVID-19 antibodies. Conclusion: Panbio™ COVID-19 Ag Rapid Test was found to have 93.4% overall sensitivity and relatively low overall specificity (37.9%). Rapid antigen testing using Panbio™ COVID-19 Ag Rapid Test Device can be effectively used to scale up mass testing to interrupt transmissibility of COVID-19 infection by generating quick result.

Surgical Attitudes And Preferences Regarding Choice Of Anaesthesia Amongst Orthopaedic Surgeons.

BACKGROUND: Regional anaesthesia is choice of anaesthesia for orthopaedic surgery due to lower side effects such as nausea, vomiting, postoperative pain and early mobilization. Despite of this, some orthopaedic patients refuse this modality. This study was conducted to interrogate the surgeons about their choice of anaesthesia in order to gain some insights into the concerns of surgeons and to change their minds and choose a safer mode of anaesthesia. The aim of the study was to assess the surgeons' fears and their perception about regional anaesthesia. METHODS: After institutional approval, thirty surgeons from three different tertiary care hospitals were interviewed. They were asked questions as per the questionnaire to choose choice of anaesthesia for their patients. RESULTS: After regional anaesthesia, 27.6% of respondents were concerned about paralysis and neurological disorders, 34.5% about seeing and hearing whatever is happening in theatre, 17.2% about perioperative pain, 24.1% about backache and 24.1% about delayed discharge. The most important reason to change their mind was the reassurance that the complications are not as frequently as they thought their patient would receive after a block. CONCLUSIONS: Due to the lack of information on regional anaesthesia and the risks of general anaesthesia, orthopaedic surgeons' fears and conceptions about regional anaesthesia are distorted. Anaesthesiologists should be aware of the concerns of the surgeons as well as the patients and should be willing to discuss the concerns with them and suggest the safest way to receive anaesthesia with evidence-based data.

Dermatology Life Quality Index In Patients Of Psoriasis And Its Correlation With Severity Of Disease.

BACKGROUND: Patient suffering from psoriasis can be severely affected in their day to day activities and it may also result in reduced work efficiency and absenteeism from work leading to financial burden on the patient's family. This study was conducted using Dermatology Life Quality Index to assess the quality of life of a patient suffering from psoriasis being treated at a military hospital. METHODS: This cross-sectional study was conducted in the outpatient unit of Department of Dermatology, Combined Military Hospital Abbottabad from 1st October 2013 to 31stJune 2014. The demographic data and Dermatology Life Quality Index of patients of psoriasis were recorded using a standard questionnaire and their final score was calculated to assess the effect of disease on patient's life. Extent/ severity of disease were assessed according to the body surface area involved. The data was analysed using SPSS- 18. Mean and SD for numerical variables and frequencies and percentages for categorical were calculated. RESULTS: A total of 160 patients fulfilling the inclusion criteria were included in the study. Mean age of the patients was 40.48 years (±12.58 years) with minimum age of 18 years and maximum of 74 years. 118 patients were males were (73.8%) and 42 were females (26.2%). Twenty (12.5%) patients had no effect on their life by the disease while 5 (3.1%) had extremely large effect. Most patients, i.e., 68 (42.5%) had moderate effect on their lives. 69 patients had mild psoriasis as per body surface area involved, 70 had moderate disease and 21 had severe disease. CONCLUSIONS: Psoriasis affects quality of life of patients not only physically but also psychologically and financially even when patients are under treatment. Psychological aspects also need to be addressed while treating the physical morbidity.

Effect Of Dexamethasone Versus Placebo For Improved Recovery In Patients Undergoing Anaesthetic Interventions For General Surgical Procedures.

BACKGROUND: Endotracheal intubation is one of the basic prerequisites of general anaesthesia. Recovery of patients is delayed due to the development of post-operative nausea, vomiting, sore throat and shivering. This study was conducted to determine role of dexamethasone for improved recovery of patients. METHODS: This randomized controlled trial was performed in the Department of Anaesthesia, Ayub Teaching Hospital, Abbottabad from June to November 2018. One hundred and twenty-two consenting patients of both genders, aged between 18-60 years, American Society of Anaesthesiologists (ASA) I and II, scheduled for general surgeries of 60-180 minutes duration under general anaesthesia were included. Patients with long duration surgeries, anticipated difficult airways, nasogastric tube in situ, upper respiratory tract infections, on steroid therapy and critically ill and emergency surgeries were excluded. They were randomly allocated into two groups by lottery method as dexamethasone (group A, n=61) or Placebo (group B, n=61). Postoperative nausea, vomiting, sore throat was observed at 2, 12 and 24 hours, shivering was observed at 2 hours only and patient satisfaction at 24 hours post-operatively. RESULTS: Group A patients had statistically proven better outcomes at 2, 12 and 24 hours for post-operative sore throat, nausea and vomiting, shivering was controlled in 24.5% p-value (0.006). Patient satisfaction was found in 83.6% of group A patients.. CONCLUSIONS: Thus, dexamethasone is effective drug for prevention of postoperative nausea, vomiting, sore throat and shivering in general surgical procedures thus improving patient satisfaction and their early discharge.

Efficacy Of Intravenous Lignocain Vs Sevoflurane In Prevention Of Coughing And Desaturation At Extubation In Children.

BACKGROUND: Inadvertent coughing and desaturation are the most commonly faced and feared respiratory complications in post-anaesthesia period. The study was done to compare the efficacy of intravenous lignocaine versus sevoflurane in prevention of coughing and desaturation at extubation in children less than 6 years of age. METHODS: This Randomized Control Trial was carried out from May 2013 to May 2016, at Combined Military Hospital Nowshera after obtaining approval from the hospital ethics committee (IREC-0003/5/13/Aneas). Children aged three months to six years undergoing surgical procedures requiring the placement of definitive airway were randomly assigned into two groups. Patients were anaesthetized by standardized balanced anaesthesia technique. In Group A (n=355), three minutes prior to extubation lignocaine 2% was used intravenously. In Group B (n=355), isoflurane was switched off, breathing circuit changed and sevoflurane started at minimum alveolar concentration (MAC 3-4%) for 3 minutes prior to extubation. Assessment for extubation was clinical. Oxygen saturation and severity of coughing were noted for 5 consecutive minutes, after extubation. RESULTS: In group-A, 156 patients were less than 2 years of age while in group-B, 135 patients were less than 2 years old. In group-A, 199 and in group-B, 220 children were 2-6 years of age respectively. Post stratification the p-value for weight was 0.17 (p-value >0.05) and t-statistic was 1.36. Post stratification p-value for gender was 0.12 (p-value>0.05) and chi square statistic was 2.49. Group A had more eventful extubation with 270 cases of cough (76%) as compared to group-B where it was noted in 199 cases (56%). Similarly, desaturation was observed in 85 cases in group-A (24%) as compared to 28 cases (8%) in group-B. The difference between the groups was statistically significant. CONCLUSIONS: Sevoflurane based anaesthetic vapours mixture causes statistical significant prevention from events like coughing episodes and desaturation in post-extubation in children less than six years of age undergoing elective surgery.

MORBIDITY OF SURGERY IN PREVIOUSLY UNDIAGNOSED CIRRHOTIC PATIENTS.

BACKGROUND: Undiagnosed cirrhotic patients are frequently encountered during routine and emergency surgery. These patients have a higher incidence of blood loss & wound infection, resulting in prolonged hospital stay. This study was conducted to highlight the possible complications which result in prolonged hospital stay in these patients. METHODS: A total of 38 patients were incidentally found to have cirrhosis out of a total of 1560 patients who underwent abdominal operation. Diagnosis was confirmed on per-operative liver biopsy and was suspected preoperatively in patient having abnormal liver function test. Per-operative bleeding, postoperative wound infection and hospital stay was compared in cirrhotic and non-cirrhotic patients. RESULTS: The mean blood loss was 310 ml in cirrhotic patients as compared to 205 ml in non-cirrhotic patients which was statistically significant (p-value 0.008). Post-operative infection rate was 21% in cirrhotic patients compared to non-cirrhotic patients 5%. Significance was tested using Pearson Chi square test (0.042). The Average hospital stay was 10 days in cirrhotic patients and 7.5 days in non-cirrhotic patients respectively which was statistically significant (p-value 0.006). CONCLUSION: There is statistically significant difference in per-operative bleeding, wound infection and hospital stay in cirrhotic and non-cirrhotic patients.

PATTERN OF INJURIES SEEN IN MASS CASUALTIES IN TERRORIST ATTACKS IN BALUCHISTAN, PAKISTAN--A THREE YEARS EXPERIENCE.

BACKGROUND: As a front line state in war against terror, Pakistan has been a victim of terrorism, for the last many years & Baluchistan has been the hub of all such terror activities. The objective of this study was to determine the incidence and type of injuries in mass casualties in terrorist activities in Baluchistan. METHODS: The study was done by the review of the record of all patients of terrorist attacks who were admitted in Combined Military Hospital (CMH) Quetta from 27th Aug 2012 to 31st Jul 2015. The final injuries sustained by the victims were documented in the patient charts after repeated examination. The data was collected from these patient charts. Data was analysed using SPSS-21. Frequency & percentages of different injuries was calculated to determine the injury pattern. RESULTS: A total of 3034 patients reported to the hospital (n-3034), 2228 were admitted (73.4%). Out of the injured, 1720 (56.69%) were patients of multi system trauma, whereas 1314 (43.3%) had a single site injury. Out of these 537 patients had fractures of long bones (17.6%), those with head & spinal injuries with neurological deficit were 455 (14.9%), 266 had abdominal injuries requiring surgical intervention (8.7%), 75 (2.47%) had thoracic injuries were whereas 25 (0.82%) were vascular injuries, requiring emergent limb saving surgeries. Sex ratio was M/F=5.7: 1 Mean hospital stay was 6.31 days. CONCLUSION: Majority of the injured had multisystem injuries; therefore the hospital should have a well-trained multi-disciplinary team of surgeons. In addition to general surgery, the subspecialties' should include orthopaedics, vascular, thoracic and neurosurgery.

Diagnostic accuracy of ultrasonography in acute appendicitis.

BACKGROUND: The diagnosis of acute appendicitis is mainly clinical and to augment the clinical diagnosis ultrasonography and Computerized Tomographic Scan of the abdomen are also being used to help in diagnosis of the disease; which all carry some inherent limitations. This study was done to establish diagnostic accuracy of Ultrasonography (USG) in acute appendicitis taking histopathology of removed appendix as the gold standard. METHODS: This cross-sectional validation study was conducted in Radiology Department, Military Hospital and Combined Military Hospital Rawalpindi from July 2007 to January 2008. Sixty cases of clinically suspected acute appendicitis were selected on non-probability convenience sampling technique. All of them underwent ultrasound evaluation. Diagnostic accuracy of USG was calculated keeping histopathology of the removed appendix as gold standard whenever appendectomy was carried out. RESULTS: Out of 60 patients whose USG of right lower quadrant was performed, 30 patients were correctly diagnosed as having acute appendicitis on USG out of 34 finally diagnosed cases based on histopathology. Similarly we picked 12 normal appendices out of 26 non-appendicitis patients. This showed that US scan has sensitivity of 88%, specificity of 92%, positive predictive value of 94%, negative predictive value of 86%, and overall accuracy of 90%. The most accurate appendiceal finding for appendicitis was a diameter of 7 mm or larger followed by non- compressibility of inflamed appendix. CONCLUSION: Ultrasonography has high accuracy in diagnosing acute appendicitis and reduces negative appendectomies. Greater than 6-mm diameter of the appendix under compression is the most accurate USG finding with high positive predictive value for the diagnosis of acute appendicitis.
