RESUMO
A 64-year-old male had an awake right nasal fiber-optic intubation with an endotracheal tube for open reduction and internal fixation of bilateral displaced mandibular fractures. After induction of anesthesia, an 18 Fr nasogastric tube (NGT) was inserted through the left nostril and was secured. The patient required high flow rates to deliver adequate tidal volumes with the ventilator. A chest x-ray done in the postanesthesia care unit revealed a malpositioned NGT in the left lower lobe bronchus, which was immediately removed. The patient was extubated on postoperative day 2. Various traditional methods, such as aspiration of gastric contents, auscultation of gastric insufflations, and chest x-ray are in use to detect or prevent the misplacement of an NGT. These methods can be unreliable or impractical. Use of capnography to detect an improperly placed NGT should be considered in the operating room as a simple, cost-effective method with high sensitivity to prevent possibly serious sequelae of an NGT placed within the bronchial tree.

Cryoneurolysis has been utilized for numerous persistent and intractable painful conditions, including phantom limb pain and postsurgical pain. Although there are reports on the effectiveness of cryoneurolysis in various regions, including the intercostal nerves, the subcostal nerve remains a common culprit of chronic pain for which the literature is scarce. Different modalities are commonly utilized to address subcostal neuropathic pain, such as non-opioid pharmacotherapy, including nonsteroidal anti-inflammatory drugs (NSAIDs) and anticonvulsants, site-specific regional anesthesia, and radiofrequency ablation.However, the analgesia provided by these modalities is often inadequate or short-lived. Cryoneurolysis of the subcostal nerve remains largely unexplored and may provide a promising solution.Here, we present the first technical description of ultrasound and fluoroscopic guided percutaneous cryoneurolysis of the subcostal nerve and the case of a patient with 14 years of lower thoracic rib pain who failed multiple interventions but achieved complete pain resolution at the three-month follow-up through this procedure.
RESUMO
Postherpetic neuralgia (PHN) is a chronic neuropathic pain syndrome that is a direct consequence of the reactivation of varicella zoster virus (VZV). It manifests as neuropathic pain, which is pain that occurs because of dysfunction or damage of the nerves that carry sensations to the brain, and this typically persists for months to years after herpes zoster. Current conservative management for PHN includes a combination of topical agents (i.e., lidocaine and capsaicin) and systemic therapy (i.e., serotonin and norepinephrine reuptake inhibitors (SNRIs), gabapentin, pregabalin, and opioids). For refractory cases, with persistent intractable pain, more invasive interventional techniques can be used as pain-relieving measures to improve the patient's quality of life. This report presents a patient with upper limb PHN who responded to peripheral nerve stimulation (PNS) after he failed to obtain sufficient pain relief with conservative management.
RESUMO
The pudendal nerve is situated deep within the pelvis and is a challenge to target for pain interventions due to the theoretical risk of incontinence with manipulation. The management of pudendal neuralgia using cryoablation is currently limited as it has historically required computed tomography (CT) guidance by interventional radiologists. Through this report, we describe a safe, reproducible, ischiorectal fossa approach to pudendal nerve cryoablation with a handheld device utilizing anatomical landmarks, nerve stimulation, and fluoroscopy. Two patients with longstanding pelvic pain and positive response to diagnostic pudendal nerve blocks underwent bilateral cryoablation of the pudendal nerves. This procedure was performed with the patients in prone positioning and percutaneous insertion of a cryoablation probe medial to the ischial tuberosity and lateral to the rectum. Correct positioning on the pudendal nerve was achieved with nerve stimulation eliciting visible anal sphincter contraction, and fluoroscopic imaging of the probe relative to the ischial spine. The probe was set to -88 Celsius for 108 seconds and a total of two cycles were performed. Pain reduction was reported for 3-4 months and repeat cryoablation was similarly efficacious with no evidence of incontinence. This technique, we believe minimizes risks and simplifies cryoablation to be performed on an outpatient basis by more pain physicians.
RESUMO
Urticaria within one hour of lidocaine injection is a sign of type I (immediate) hypersensitivity to lidocaine, yet most patients suspected of having a lidocaine allergy do not exhibit urticaria. Aside from being a sign of a rare lidocaine allergy, urticaria can also be a symptom of COVID-19. COVID-19 patients who experience urticaria after receiving lidocaine require careful evaluation to determine the cause. Here, we present a case of a patient exhibiting urticaria one hour after a lidocaine injection for the Pecto-intercostal nerve block to treat COVID-19-induced costochondritis.
RESUMO
Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by chronic pelvic, perineal, or bladder pain in addition to lower urinary tract symptoms. The etiology of this condition is not fully understood, which presents a challenge for effective therapeutic intervention. Current treatment guidelines recommend the use of multimodal pain management strategies including behavioral/non-pharmacologic, oral medications, bladder instillations, procedures, and major surgery. However, the safety and efficacy of these modalities vary, and there is currently no optimal treatment for the management of IC/BPS. The pudendal nerves and superior hypogastric plexus, which together mediate visceral pelvic pain and bladder control, are not addressed in the current guidelines but may serve as a therapeutic target. Here, we report improvements in pain, urinary symptoms, and functionality following bilateral pudendal nerve blocks and/or ultrasound-guided superior hypogastric plexus blocks in three patients with refractory IC/BPS. Our findings provide support for the use of these interventions in patients with IC/BPS unresponsive to prior conservative management.
RESUMO
Renal transplantation is the most common solid organ transplant in the United States. Post-transplant neuralgia is a frequent complication and may be due to infection, medication side effects, post-transplant lymphoproliferative disorder (PTLD), or the procedure itself. This case report describes an instance of post-renal transplant neuralgia in a 70-year-old Caucasian female. Diagnostic nerve blocks revealed the involvement of the ilioinguinal, genitofemoral, and lateral femoral cutaneous nerves. The case report details management that included nerve blocks, radiofrequency ablation (RFA), and a permanent peripheral nerve stimulator (PNS) implant.
RESUMO
Olfactory and gustatory dysfunction, including anosmia, parosmia, ageusia, and dysgeusia, are common long-term symptoms of coronavirus disease 2019 (COVID-19) infection. These symptoms can have a severe impact on quality of life of a patient, including psychological well-being. Stellate ganglion block (SGB) has recently been explored as a potential therapeutic intervention for these symptoms. In this case series, we present six patients with long-term COVID-19 symptoms and we detail how their symptoms evolved after an SGB. All SGB were performed under ultrasound guidance by the same physician. Patients had a right SGB during the initial visit, followed by a left SGB at a subsequent visit. All but one patient reported improvements in olfaction and gustation after the SGB. Our findings suggest that SGB may be a promising therapeutic intervention for patients with olfactory and gustatory dysfunction related to long-term COVID-19 symptoms. Further research is needed to confirm these findings and to explore the optimal treatment protocol.
RESUMO
BACKGROUND: Arrhythmias resulting in cardiac arrest during electroconvulsive therapy have been reported. Most reported cases of cardiac arrest had asystole as the initial rhythm. Pulseless electrical activity as an initial rhythm of cardiac arrest during electroconvulsive therapy has never been reported. Also, thromboembolism after inflation of pneumatic tourniquet during lower limb surgery has been reported but never following tourniquet inflation during an electroconvulsive therapy. CASE PRESENTATION: We report a case involving an 81- year- old female who presented to us for an electroconvulsive therapy for severe depression and developed pulseless electrical activity immediately after electroconvulsive therapy. She was successfully resuscitated and was later found to have bilateral pulmonary emboli with a complete occlusion of the right lower lobe pulmonary artery. The source of embolus was from her left lower extremity deep venous thrombus, which we believe, got dislodged intraoperatively after inflation of pneumatic tourniquet. Our patient not only survived the massive pulmonary embolus, but also showed significant improvement in her mental status compared to her pre-admission level at the time of discharge to a sub-acute rehabilitation centre. CONCLUSION: We recommend that patients who are elderly and at high risk of thromboembolism should selectively undergo a preoperative doppler ultrasound for deep venous thrombosis. Also, selective application of tourniquet in the upper limb, to monitor for seizure activity, would reduce the incidence of pulmonary thrombo-embolism as embolic events are significantly less from deep venous thromboses of upper extremities when compared to lower extremities.
RESUMO
Ketamine, a nonselective NMDA receptor antagonist, is used widely in medicine as an anesthetic agent. However, ketamine's mechanisms of action lead to widespread physiological effects, some of which are now coming to the forefront of research for the treatment of diverse medical disorders. This paper aims at reviewing recent data on key nonanesthetic uses of ketamine in the current literature. MEDLINE, CINAHL, and Google Scholar databases were queried to find articles related to ketamine in the treatment of depression, pain syndromes including acute pain, chronic pain, and headache, neurologic applications including neuroprotection and seizures, and alcohol and substance use disorders. It can be concluded that ketamine has a potential role in the treatment of all of these conditions. However, research in this area is still in its early stages, and larger studies are required to evaluate ketamine's efficacy for nonanesthetic purposes in the general population.
RESUMO
Most amyotrophic lateral sclerosis (ALS) patients require enteral feeding, thus necessitating placement of a gastrostomy tube (G-tube) for worsening dysphagia. This case report discusses the use of bilateral thoracic paravertebral nerve blocks (TPVB) in two patients with ALS to facilitate an open G-tube placement to avoid ventilatory assistance.
RESUMO
While it has been shown that a paravertebral block provides effective postoperative analgesia for patients undergoing thoracic surgeries, including first rib resection, this is the first reported case of a paravertebral catheter used for perioperative analgesia in a patient undergoing first rib resection. We present the case of a 76-year-old woman with right upper extremity swelling who underwent infraclavicular first rib resection for venous thoracic outlet syndrome. Continuous infusion of ropivacaine through a T1 paravertebral catheter, which was placed before induction of general anesthesia but after T1 and T2 paravertebral blocks, provided effective postoperative pain control. Our experience suggests that paravertebral catheter infusions of local anesthetics may be effective adjuncts to general anesthesia in patients undergoing first rib resection and warrants further investigation.

BACKGROUND AND AIMS: Atrial fibrillation (AF) is the most common arrhythmia seen clinically. Due to the lack of literature and guidelines on maternal AF as a postoperative complication following cesarean delivery (CD), we undertook a study to characterize parturients who developed AF following CD and to evaluate arrhythmia management and outcomes in this patient population. METHODS: After receiving ethics committee approval, a retrospective chart review was performed to determine the incidence, possible risk factors, treatment, and outcome of women who developed AF following CD performed between 2003 and 2012 at New York Methodist Hospital in Brooklyn, New York. RESULTS: A total of 17,039 CDs were performed at New York Methodist Hospital from 2003 to 2012. Of these, seven parturients developed AF after CD. The incidence of AF following CD in this patient population was 1:2,434 (0.04%). The age range was 26-41 years, with a median of 33 years. All 7 parturients were at term or postterm. Two deliveries were elective and five were emergent. Two of the seven parturients had prior history of paroxysmal AF. One patient was identified as having mitral regurgitation. All seven had low levels of serum magnesium postoperatively. Out of the seven, two parturients had spontaneous conversion to normal sinus rhythm, one required electrical cardioversion and four required pharmacologic cardioversion. CONCLUSIONS: Postoperative AF (POAF) exists as a rare complication in women who undergo CD with an incidence of 0.04% in our patient population. All parturients in our study were noted to have hypomagnesemia in the postoperative period. Occurrence of AF increased length of hospital stay and utilization of hospital resources.
RESUMO
The pudendal nerve block (PNB) is widely used for regional anesthesia during obstetric and anorectal procedures, but its role in urologic procedures has not been thoroughly studied. While transvaginal PNB is relatively straightforward, PNB in male patients often requires imaging guidance due to difficulty appreciating anatomic landmarks. We review the PNB and relevant sonoanatomy, and describe its analgesic efficacy in three male patients undergoing urethroplasty for urethral stricture. In this procedure, the patient was placed in lithotomy position, the ischial tuberosity was palpated, and the sacrotuberous ligament and pudendal artery were identified using ultrasound. Ropivacaine was injected medial to the pudendal artery and disappearance of muscle twitch was demonstrated. Two patients reported well-controlled pain at 24 hours postoperatively. One reported perineal pain requiring additional analgesia. All patients were discharged on postoperative day 1 without complications. Ultrasound-guided PNB provides safe and reasonably effective pain control to male patients undergoing urologic procedures.
RESUMO
We present a case of regional analgesia utilized in a 43-year-old woman with Bernard-Soulier syndrome (BSS) undergoing a Nuss procedure for the treatment of pectus excavatum. BSS is an extremely rare bleeding disorder (1:1,000,000) associated with prolonged bleeding times, giant platelets, and thrombocytopenia. Due to the rare incidence and heterogeneity in bleeding predisposition due to BSS, there is no clear consensus in management of such cases, and to our knowledge, utilization of regional analgesic techniques have not been described in the literature. The Nuss procedure is considered "minimally" invasive, and epidural analgesia is frequently utilized at our institution. Due to our patient's heterozygous presentation of BSS and mild history of bleeding, a modified perioperative multimodal analgesic plan was chosen which included bilateral single injection paravertebral nerve blocks (PVBs). Our report describes successful utilization of PVBs in a patient with BSS and our approach to this rare hereditary condition.
RESUMO
BACKGROUND AND AIMS: To assess the efficacy of bilateral thoracic paravertebral nerve blocks (PVB) in providing procedural anesthesia and post-procedural analgesia for placement of percutaneous radiologic gastrostomy tubes (PRG) in patients with amyotrophic lateral sclerosis (ALS). METHODS: We prospectively observed 10 patients with ALS scheduled for PRG placement that had bilateral thoracic PVBs at thoracic 7, 8, and 9 levels with administration of a mixture of 3 mL of 1% ropivacaine, 0.5 mg/mL dexamethasone, and 5 µg/mL epinephrine at each level. The success of the block was assessed after 10 minutes. PRG placement was done in the interventional radiology suite without sedation. All patients were followed up via phone 24 hours after the procedure. RESULTS: All 10 patients had successful placement of PRG with PVBs as the primary anesthetic. Segmental anesthesia over the surgical site in all cases was successful with first attempt of the blocks. Three patients had significant hypotension after the block, requiring boluses of vasopressors and intravenous fluids. All patients reported high levels of satisfaction and sleep quality on the night of the procedure. CONCLUSIONS: Bilateral thoracic PVBs provided satisfactory procedural anesthesia and post-procedural analgesia, and thus, seem promising as a safe alternative to sedation in ALS patients having PRG placement.
RESUMO
BACKGROUND: There is an increasing use of electronic health records in hospitals across the United States. The speed and accuracy of residents in documenting electronic health records has been insufficiently addressed. METHODS: We studied resident typing skills at New York Methodist Hospital. Participating residents typed a standard 100-word alphanumerical paragraph of a patient's medical history. Typing skills were assessed by calculating the net words per minute (WPM). Typing skills were categorized as follows: (1) fewer than 26 net WPM as very slow; (2) 26 to 35 net WPM as slow; (3) 35 to 45 net WPM as intermediate; and (4) greater than 45 net WPM as fast. Residents were further categorized into (1) American medical graduates; (2) American international medical graduates; and (3) non-American international medical graduates. RESULTS: A total of 104 of 280 residents (37%) participated in the study. There was equal representation from various specialties, backgrounds, and all postgraduate levels of training. The median typing speed was 30.4 net WPM. Typing skills were very slow (34 of 104, 33%), slow (28 of 104, 27%), intermediate (29 of 104, 28%), and fast (13 of 104, 12%) among the residents. Typing skills of non-American international medical graduates (mean net WPM of 25.9) were significantly slower than those of American medical graduates (mean net WPM of 35.9) and American international medical graduates (mean net WPM of 33.5). CONCLUSIONS: Most residents (60%, 62 of 104) who participated in the study at our institute lacked typing skills. As the use of electronic health records increases, a lack of typing skills may impact residents' time for learning and patient care.
