Published: November 2022

ABSTRACT
The 2010 M 7.0 Haiti earthquake provided the impetus to reconsider historical earthquakes in Hispaniola (Bakun et al., 2012). That earthquake also shed new light on complex fault systems along Haiti’s southern peninsula (Douilly et al., 2013; Saint Fleur et al., 2015). Recently, the 2021 M 7.2 Nippes earthquake (Calais et al., 2022; Douilly et al., 2022), and a recent study reconsidering the 1860 sequence (Martin et al., 2022) further underscored the complexity of fault systems and large earthquake ruptures along the peninsula. Motivated by these studies and recent geological investigations (Prentice et al., 2010; Saint Fleur et al., 2020), we reconsider the 3 June 1770 Haiti earthquake to explore the conventional assumption that it was the last major (M ≥7.5) earthquake along the Enriquillo–Plantain Garden fault (EPGF). Accounts provide compelling evidence for substantial liquefaction in the Cul-de-Sac plain, one or more likely landslide-driven tsunami in Gonaïves Bay, and extensive landsliding that created at least three documented landslide dams. We consider three end-member rupture scenarios that are consistent with available constraints: two scenarios with M 7.7 and rupture lengths of 150–170 km, and one scenario with a ∼90 km rupture and M 7.5. Absent future work to identify and date paleoevents along the southern peninsula, none of these scenarios can be ruled out. Our preferred rupture model extends from the Miragoâne pull-apart to near la Selle mountain, with a rupture length of 127 km, M 7.6, and a high stress drop. Rupture could have been on the EPGF or on an oblique thrust fault associated with overthrusting of the Massif de la Selle. The results do support the conclusion that the 1770 earthquake was the last major earthquake in southern Haiti, with a magnitude upward of M 7.5 and significantly more severe shaking in southern Haiti than during the 2010 earthquake.

Reconstruction of midfacial traumatic defects secondary to a gunshot wound (GSW) is one of the most challenging head surgeries. The high impact on the functional and aesthetic quality of life, and the small margin of error to achieve a successful outcome are significant hurdles in the surgical treatment of these cases. Here we report a 33-years old patient who suffered a GSW with an entrance wound penetrating between the soft and hard palate and an exit wound on the right malar region. A description of the case and a systematic review of the literature were conducted. The treatment depends on the type of weapon used, deforming characteristics of the bullet, kinetic energy, place of impact, and general conditions of the patient. GSW generate a particular injury due to their special trauma kinematics. In this case, our patient required extensive reconstructive surgery with interposition of costal cartilage to recover velopharyngeal structure and function, patients treated with this surgical strategy develop fewer complications such as infection, shrinkage, scarring. As demonstrated by this case report, the result can be satisfactory. In order to provide the most beneficial results for the patient, surgical techniques are evolving continuously, improving both structure and function, and increasing the quality of life of the patients. Free flaps are preferred because of the good results reported. Patients treated with this surgical strategy develop fewer complications such as infection, shrinkage, scarring. As demonstrated by this case report, the result can be satisfactory.

Lower limb surgeries may be performed under local, regional (spinal or epidural) or general anesthesia, but neuraxial blockade is the preferred mode of anesthesia. Sub-arachnoid block or Spinal anaesthesia is the most common central block used in a surgical setting, which is being the most versatile and commonly used regional block. With increasing use of hyperbaric bupivacaine for sub arachnoid block, their limitations like prolongation of onset of sensory and motor blockage effect, short duration of action and early postoperative requirement of an analgesic agent, require an intrathecal adjuvant to these local anaesthetic agents for a complete satisfactory period of anaesthesia and patient satisfaction. The aim of this study was to compare and evaluate the effect of Dexmedetomidine with MgSO4 (50%) intrathecally as an adjuvant for the characteristics of sensory and motor blockage for lower limb orthopedic surgery under subarachnoid block along with bupivacaine (0.5%). : Participants were randomly divided into two groups of 40 participants each. Group D (n=40) received Bupivacaine + dexmedetomidine, Group M (n=40) received Bupivacaine + MgSO4. Under strict aseptic and antiseptic precaution subarachnoid block was performed. Mixture of drugs according to group assign was injected. Assessment of sensory and motor characteristics was done. Inj. Dexmedetomidine as an adjuvant in spinal block, seems to be superior to intra-thecal MgSO4 as it has faster onset, longer duration of action, prolonged analgesia in comparison with Magnesium Sulphate without significant hemodynamic alterations. Dexmedetomidine, as an adjuvant to Inj. Bupivacaine intra-thecally in sub-arachnoid block, has faster onset, longer duration of action, prolonged analgesia in comparison with Magnesium Sulphate.

: To compare the efficacy of USG guided central venous catheterisation at internal jugular vein (IJV) and at the Pirogoff’s confluence [IJV, subclavian vein (SCV), Brachiocephalic Vein (BCV)].: A prospective, comparative, randomized, hospital based study was conducted on 100 patients requiring central venous access. After explaining the study to the selected patients, they were randomized into two groups with the use of sealed envelope method i.e. group A (Central venous cannulation of IJV) and group B (central venous cannulation of Pirogoff’s confluence of IJV, SCV, BCV). Data was collected with respect to the efficacy of USG guided cannulation on the basis of time for visualisation, access time, number of attempts, time to CVC, total time of procedure, length of catheter inserted. Any complications encountered were recorded.: There was no difference between number of attempts in either of groups, mean visualization, access time and time to CVC was longer in group B with statistically significant difference. Mean length of catheter inserted was shorter in group B with statistical significant difference. Procedure time required was comparatively more in group B. : The results indicated that Ultrasound guided cannulation of group A is efficacious than group B in terms of time required to culminate the procedure as well as complications but cannulation of Pirogoff’s confluence is a novel approach giving easier access, better visualisation and length of catheter inserted is lesser than IJV.

Hypotension is a common complication, subsequently spinal anaesthesia in lower segment caesarean section, which can cause adverse maternal & foetal outcomes. A new decisive research area in obstetric anaesthesia is prevention & early treatment of spinal hypotension to improve maternal & foetal outcomes. A novel parameter, Perfusion index (PI) is tried during sub arachnoid block for predicting hypotension in lower segment caesarean section (LSCS). In this study, 60 parturient belonging to ASA status 1 or 2 with apparent pregnancies scheduled for elective LSCS received spinal anaesthesia with 2ml of 0.5% heavy bupivacaine by using an orange (25G) Quincke needle at L3-L4 or L4-L5 interspinous space. Haemodynamics & perfusion index were recorded at regular intervals. Baseline perfusion index was correlated with degree of hypotension by using Receiver Operative Characteristic curve. Baseline perfusion index & other parameters were correlate by Karl Pearson correlation method. : In our study 34.5% incidence of hypotension among study theme & momentous correlation between fall in systolic blood pressure from baseline & baseline perfusion index (r = 0.436; P &#60; 0.05). The optimal utmost point for perfusion index was found to be 3.5 with a sensitivity of 37% & specificity of 97%. A higher incidence of hypotension was found in Parturient having baseline perfusion index more than 3.5 following sub arachnoid block in elective LSCS.

Published: November 2022

Awake fiberoptic intubation requires adequate airway anaesthesia along with good sedation to achieve patient cooperation during intubation without respiratory depression and hypoxia.The purpose of this study was to compare dexmedetomidine alone and dexmedetomidine with ketamine in order to achieve an ideal regimen during awake fiberoptic intubation by providing sedation, good intubating conditions, better hemodynamic stability, and patient satisfaction.This prospective, randomised, double-blind clinical trial included 60 patients who were scheduled for elective surgery under general anaesthetic and required nasotracheal intubation. Patients were randomly assigned to two groups of 30 each, with ages ranging from 18 to 65 years and ASA grades I and II. All patients received an inj. dexmedetomidine bolus at 1 mcg/kg over 10 min. followed by a study drug depending on the group. In Group A, patients will receive an inj. ketamine 15 mg bolus and a 20 mg/hr ketamine infusion, whereas those in Group B will receive a normal saline bolus and infusion till completion of intubation. Sedation by Ramsay sedation scale (RSS), intubation response (by coughing score and grimace score), hemodynamic stability was observed during awake fiberoptic intubation, and patients' satisfaction by visual analogue score (VAS) and recall of events were assessed post operatively at 24 hours. In Group A with greater hemodynamic stability compared to Group B, RSS and Post-Operative Vas Score were more successfully attained. A combination of dexmedetomidine and ketamine provides the optimum sedation, hemodynamic stability, and patient satisfaction during awake fiberoptic intubation.

The Adjuvants added to local anaesthetic increases the duration of post-operative analgesia and decreases the analgesic requirement in post-operative period. The study was conducted with the intent of comparing post-operative analgesic effect of Dexamethasone and Dexmedetomidine in ultrasound guided Brachial Plexus Block. A prospective, randomised, double blind study to compare post-operative analgesic effect of Dexamethasone and Dexmedetomidine as adjuvant to 0.2% Ropivacaine in Ultrasound Guided Brachial Plexus Block. 60 patients belonging to ASA I and ASA II scheduled for upper limb surgeries were included in the study after taking informed consent. Group A received 20ml of 0.2% Ropivacaine with 8mg of Dexamethasone. Group B received 20ml of 0.2% Ropivacaine with 50 µg of Dexmedetomidine. Our primary objective was to compare the time to first request for analgesia in both the groups. Secondary objective was to compare duration of sensory and motor block in post-operative period and to compare overall requirement for analgesia in 24 hours in both the groups. The mean duration of motor block in Dexamethasone group was 635.47 ± 26.29 minutes and in Dexmedetomidine group was 827.47 ± 54.62 minutes. Similarly, mean duration of sensory block was 681.5 ± 27.19 minutes in Dexamethasone group and 877.17 ± 52.85 minutes in Dexmedetomidine group. The mean duration of time to first rescue analgesic was 709.67+18.47 minutes in dexamethasone group and 910.2 ± 51.66 minutes in Dexmedetomidine group. Total analgesia given had significant statistical difference of 0.004 between the two groups, with mean of 1.23 ± 1.17 in Dexamethasone group and 0.4 ± 0.56 in Dexmedetomidine. However, at 2hr, 4hr, 8hr, 12hr, 18hr and 24 hr the difference in VAS scores was significant (p value &#60;0.0001). Dexmedetomidine is better than Dexamethasone in prolonging duration of analgesia of the Brachial plexus block.

The obstetric population has been most vulnerable in this COVID-19 pandemic. We could not retrieve any study evaluating the safety and efficacy of anaesthetic techniques in parturients with COVID-19 undergoing caesarean delivery (CD) from South Asian Sub-continent. We, herein present the detailed clinical analysis and anaesthetic management of a case series of seven parturient with COVID-19 undergoing CD under subarachnoid block (SAB) in a tertiary care designated COVID hospital in the city of Delhi between June and December 2020. Herein, we report 7 parturients with mild COVID-19 disease undergoing CD under SAB. Our observations are that the use of SAB was associated with transient haemodynamic perturbations in terms of hypotension in 3 patients and bradycardia in one patient. The neonatal outcome was observed to be favourable. To conclude, our experience is that SAB is safe and effective for parturient with mildly symptomatic COVID-19 disease; however, was found to be associated with transient haemodynamic changes exclusively in parturients with anaemia.

Airway management in huge goiters present with challenges among anesthesiologists worldwide. Usually thyroid swelling presents with retrosternal extension, tracheal compression poses certain airway challenges. In our case there was no retrosternal extension or tracheal compression but tracheal deviation was present which make airway management difficult.55yr old male pt, weight 60 kg, moderately built, came with chief complaints of gradually increasing swelling in front of neck since 3 years. He was k/c/o systemic hypertension on regular treatment taking tab. amlodipine 5mg OD. He was having no change in voice, no other systemic illness. He was evaluated for left sided huge goitre having neck swelling of size 14 cm × 15 cm × 10 cm. The mass was extending from lower jaw to below sternal notch, get below the swelling was possible. Xray neck AP and lateral view revealed tracheal deviation to right by the mass, this patient was posted for the hemithyroidectomy considering difficult airway plan of anaesthesia was awake fibreoptic intubation (under topical anaesthesia and sedation). In this case because of tracheal deviation to right the glottic structures were distorted, view to vocal cords was obscured by left arytenoid making the airway management difficult.In general the difficulty of tracheal intubation in cases with thyroid disease is affected by compression or deviation of the trachea, the position and hardness of the tumour. Generally recommended techniques for securing airway in such patients are 1. Awake fiberoptic intubation 2. Awake direct laryngoscopy aided intubation 3. Inhalational induction. Awake fibreoptic intubation using local anaesthesia - sedation technique is a suitable option in selected group of patients having possibility of airway obstruction.

Abstract
Sanding phenomenon is a severe problem in the oil and gas fields found in weak unconsolidated formations. While previous experimental researches mostly studied single-phase fluid flow, it rarely happened in real reservoirs. This study presents a novel approach to investigating sand production mechanism from multiphase fluid production through experiment of large specimen size, and a coupled Computation Fluid Dynamics – Discrete Element Method (CFD-DEM) modelling for two-phase flow. The sand production experiments on a weak artificial sandstone were conducted under one-phase and two-phase flow conditions: water flow in water-saturated and gas flow in water-saturated samples using a customized High-Pressure Consolidation System (HPCS). The coupled CFD-DEM numerical simulations of similar conditions were conducted to capture the salient features of sanding behaviour at micro-levels. The discontinuous nature of sand particles and the bonds between them were modelled using DEM, whereas the continuous fluid flow was described by CFD. The experimental results showed that more sand was produced by the two-phase flow of gas through an initially water-saturated sample as compared to the single-phase water flow. The numerical results on the other hand showed different internal void fraction distributions between the two cases, which led to a faster fluid outflow and a slightly higher sand production for the multiphase flow case. The experimental and numerical results were however limited by the experiment duration and the simulation time of an otherwise on-going sand production process.

Abstract
This paper will present a case study of an Uncertainty Analysis recently performed for the Kashagan Field. This is the first full scale uncertainty work performed on the field since it came online in September 2016. The paper will describe unique challenges given Kashagan peculiarities and describe methods and approaches taken to address those.
A multi-scenario modeling workflow has been utilized to fully explore subsurface uncertainties in the decision space. First, uncertainties that were believed to have an impact on field performance based on the available data and learnings from previous studies were identified and ranked. Then, so-called categorical parameters were combined by grouping geologically relatable parameters into several scenarios with differentiating behaviors which were checked by performing screening simulation runs. This was followed by Design of Experiment (DoE) runs (Placket-Burman and Latin Hypercube), proxy modeling and Monte-Carlo analysis to aid selection of high, mid, and low models.
More than 400 simulation runs were generated resulting in a wide range of outcomes for key performance indicators, enabling the selection of high, mid, and low model realizations to evaluate future field development decisions. The approach of combining categorical parameters into multiple scenarios followed by DoE runs offered several advantages including full sampling of the uncertainty space and clearer link between geologic input and dynamic output. It also allowed to get maximum information using the lowest number of simulation runs. Communication techniques such as plumbing diagrams representing geologic scenarios were effective in discussion of study results amongst experts.
