RESUMO

The sphenopalatine ganglion (SPG) block is a simple and valuable technique that was discovered over a century ago, but, unfortunately, very few anesthesiology providers are familiar with this block. After some of our recent publications, physicians from different countries have reached out to us requesting more specifics on how we perform our version of the block. In this report, we provide a brief history of the block and demonstrate our three effective, simple, readily available, and inexpensive methodologies with images. We are proud to share that our three SPG block techniques have so far effectively relieved patients of chronic migraines, acute migraines, tension headaches, moderate-to-severe back pain, and post-dural puncture headaches.

RESUMO

OBJECTIVE: Obstetric patients who receive combined spinal-epidural (CSE) anaesthesia for elective caesarean section (CS) frequently experience intraoperative nausea and vomiting (N&V). Prophylactic therapy with antiemetic agents can have multiple adverse effects to the mother and baby. We designed a randomised clinical trial to evaluate the efficacy of electrical P6 stimulation for prophylactic N&V treatment for scheduled elective CS performed under CSE anaesthesia. METHODS: Following the Institutional Review Board approval and informed consent, a total of 180 patients were randomly allocated into three groups: (1) P6 stimulation (via a peripheral nerve stimulator), (2) intravenous (IV) antiemetics (metoclopramide and ondansetron), and (3) control (no IV antiemetic medications and no P6 stimulation), with 60 parturients in each group. RESULTS: Significantly fewer patients experienced intraoperative N&V in the P6 group (nausea 36.7% and vomiting 13.3%) and IV antiemetic group (nausea 23.3% and vomiting 16.7%) than those in the control group (nausea 73.3% and vomiting 45%; p<0.001). In addition, significantly fewer patients required rescue antiemetic medications in the P6 group (35%) and the IV antiemetic group (31.7%) than those in the control group (73.3%; p<0.001). There was no significant difference in the overall anaesthetic care satisfaction reported between the three study groups. CONCLUSION: Our data suggest that P6 stimulation is as simple and as effective as our routine prophylactic IV antiemetic treatment for prevention of N&V during CS performed under CSE anaesthesia that could be of great interest to patients and obstetric anaesthesiologists who prefer treatments with fewer potential side effects.

RESUMO

BACKGROUND AND OBJECTIVES: Postdural puncture headache (PDPH) is a severe and debilitating complication of unintentional dural puncture. The criterion-standard treatment for PDPH has been epidural blood patch (EBP), but it is an invasive intervention with the potential for severe complications, such as meningitis and paralysis. We believe this is the first ever 17-year retrospective chart review in which we compare the effectiveness of sphenopalatine ganglion block (SPGB) to EBP for PDPH treatment in postpartum patients. METHODS: We conducted a chart review of the first authors' obstetric patients who experienced PDPH from an unintentional dural puncture from a 17-gauge Tuohy needle for labor epidural from January 1997 to July 2014. Demographic characteristics, headache severity, and associated symptoms were collected prior to treatment. Forty-two patients who received SPGB and 39 patients who received EBP were identified. Residual headache, recovery from associated symptoms, and new treatment complications were compared between the 2 groups at 30 minutes, 1 hour, 24 hours, 48 hours, and 1 week posttreatment. RESULTS: A greater number of patients showed significant relief in their PDPH and associated symptoms at 30 and 60 minutes after treatment with SPGB than after treatment with EBP (P < 0.01). Only the EBP patients complained of posttreatment complications, which all resolved in 48 hours. CONCLUSIONS: A greater number of patients experienced a quicker onset of headache relief, without any new complications, from treatment with SPGB versus EBP. We believe that SPGB is a safe, inexpensive, and well-tolerated treatment. We hope that clinical trials will be conducted in the future that will confirm our findings and allow us to recommend SPGB for PDPH treatment prior to offering patients EBP.

RESUMO

Varicella zoster virus causes varicella (chickenpox). It can be reactivated endogenously many years later to cause herpes zoster (shingles). Although varicella is usually a benign disease in healthy children, it resulted in over 11 000 hospitalizations and over 100 deaths every year, in all ages, in the United States. Morbidity was considerably worse in older teenagers and adults. Between 5% and 15% of cases of adult chickenpox will produce some form of pulmonary illness. Progression to pneumonia risk factors include pregnancy, age, smoking, chronic obstructive pulmonary disease, and immunosuppression. Typically, pulmonary symptoms occur 1 to 6 days after varicella zoster infection. They often include cough, fever, and dyspnea. Treatment is a 7-day course of intravenous acyclovir for varicella pneumonia. Early intervention may modify the course of this complication. This review illustrates practical features with a case of a 34-year-old female with severe varicella pneumonia. Despite the lack of significant past medical history and absence of immunosuppression, her pneumonia worsened and by using continuous positive airway pressure mask, intubation was avoided. More important, the radiographic progression of severe varicella pneumonia is shown. This highlights how a common disease of varicella can progress in an adult and manifest with significant organ malfunction.

RESUMO

Fluoroquinolones are a class of popular outpatient antimicrobial agents with a wide spectrum of therapeutic indications for respiratory and genitourinary infections. Though the most common side effects are gastrointestinal, fluoroquinolones have been increasingly associated with neurotoxicity including peripheral neuropathy and seizures. We present here a case of a 43-year-old woman with previously resolved type I complex regional pain syndrome (CRPS) who presented with symptoms of CRPS and neurotoxicity in the setting of levofloxacin administration. Our aim is to advocate for increased caution in prescribing to patients with a history of neuropathology including CRPS.

RESUMO

Left internal mammary artery grafting is commonly used in elective coronary artery bypass graft surgery. We report a near-fatal case with graft kinking upon sternal closure due to distended, emphysematous lungs impinging on the mammary graft. After the sternum was closed, the patient suffered a severe hemodynamic deterioration. Surgical examination revealed kinking of his left internal mammary artery upon sternal closure due to distended, emphysematous lungs impinging on the mammary graft. Using an off-bypass technique, the kink in the mammary graft to the left anterior descending artery was removed by moving the origin of the left internal mammary artery to a hooded graft of a saphenous vein graft instead. In this position, the graft no longer was impinged upon by the distended emphysematous lungs. Subsequently, the patient's sternum was closed without hemodynamic impingement. Although chronic obstructive pulmonary disease is well described to increase complications in coronary artery bypass graft surgery, it has not been previously associated with the kinking of a left internal mammary artery. This report highlights another contribution that chronic obstructive pulmonary disease can make to increased morbidity following coronary artery bypass graft surgery and alerts readers to watch for this complication in susceptible patients.

RESUMO

A 32-year-old woman at 36 weeks gestation with a medical history of corrected Type 1 Arnold Chiari malformation presented with an intractable headache. When methylprednisolone and morphine treatment provided no relief, we performed 2 topical transnasal sphenopalatine ganglion blocks by applying 4% lidocaine drops into each nostril via a cotton-tipped applicator. The patient's symptoms significantly improved, and she was discharged home the same day. She has been without relapse of headaches during the 6 months of follow-up by our pain service.

RESUMO

In the present study, the availability of smoking cessation programs (SCP) was surveyed in the same randomly selected USA hospitals in 2000 and 2012. A total of 102 USA hospitals were randomly selected for this survey. Each hospital website was searched for the topic of smoking cessation. In the second phase of the survey, the main switchboard number of each hospital was anonymously telephoned and the 'stop smoking clinic' was requested. The phone survey results showed that the percentage of hospital switchboard calls that were connected to a SCP remained identical at 47% in 2000 and 2012. The results for the internet availability of SCP on hospital websites improved from 30% in 2000 to 47% in 2012. There were more hospitals that added additional SCP information (27%) compared with those that removed SCP information (15%) by 2012. Among the 57% of hospitals that showed no change in internet SCP information, 22% remained positive for such information while 35% remained negative. The phone survey of hospitals showed that 47% of USA hospitals were able to connect a caller to a SCP in the years 2000 and 2012. While there was no reduction over the 12 years, there was no increase in the percentage of hospital switchboards that connected to a SCP. Availability of SCP information on hospital web sites improved to a limited extent; increasing from 30% of sites in 2000 to 47% in 2012. Providing SCP on a hospital website is easy and free, for example adding a link to QuitNet or QuitLink. The present study adds to information gathered 12 years earlier, and is unusual in being able to provide follow-up data on the same set of hospitals studied previously.

RESUMO

BACKGROUND AND AIMS: We aimed to determine the ropivacaine concentration that provided adequate analgesia with early ambulation and minimal urinary retention or other side-effects when used with fentanyl and epinephrine for patient-controlled epidural analgesia (PCEA) after elective cesarean section. MATERIAL AND METHODS: Forty-eight patients were randomized to four groups in a double-blinded fashion. All groups received an initial 10 ml/h of epidural study solution for 24 h. The solution contained: 0.2, 0.1, 0.05, or 0.025% ropivacaine for Groups I-IV, respectively, with fentanyl 3.0 µg/ml and epinephrine 0.5 µg/ml. Patients could administer additional PCEA doses of 4 ml of their study solution with a lock-out time of 10 min. Overall satisfaction, side-effects, motor block, neurologic function, and pain using Visual Analog Scale were assessed. RESULTS: Patients in all groups showed no difference in sedation, pruritus, nausea, vomiting, and uterine cramps. Pain scores at rest were lower for Group IV than Groups I-III (P < 0.001). Twelve, five, one, and zero patients could not ambulate in Groups I-IV, respectively. Nine, nine, two, and zero (III

RESUMO

Prompted by our experience with complications occurring with apnea testing (AT), we discuss complications reported in the literature. AT is an integral part of brain death assessment. Many complications of AT have been described, including hypoxemia, arterial hypotension, tension pneumothorax and cardiac arrest. We conclude that a commonly used technique in conducting AT can create auto-positive end expiratory pressure (PEEP) and contributes to many complications. The mechanism of occult auto-PEEP in AT is discussed. Intensive care unit patients may have a compensated and asymptomatic relative hypovolemia that can be decompensated by a small amount of auto-PEEP produced by air trapping during insufflating oxygen (O2) through a 7.0 endotracheal tube (ETT). It could then lead to decreased preload, decreased stroke volume, decreased cardiac output and thus, to hypotension and a compensatory tachycardia. The placement of the standard O2 tubing (6mm outside diameter [OD]) inside the 7.0 ETT (7mm inside diameter [ID]) greatly decreased the ETT lumen (73%). We changed our practice to instead use readily available small pressure tubing to insufflate O2 for AT to avoid excessive reduction in the ETT lumen. The change from standard O2 tubing (6mm OD) to pressure tubing (3mm OD) will greatly decrease the reduction in cross-sectional area of 7.0 ETT lumen from 73 to 18% and avoid potential complications of air trapping, auto-PEEP and barotrauma. We have successfully used this new simple technique with readily available equipment to eliminate auto-PEEP in AT while preserving oxygenation.

RESUMO

The use of lignin peroxidase (LIP) as an alternative method for the removal of four catechols (1,2-dihydroxybenzene): catechol (CAT), 4-chlorocatechol (4-CC), 4,5-dichlorocatechol (4,5-DCC) and 4-methylcatechol (4-MC) typical pollutants in wastewater derived from oil and paper industries, was evaluated. The removal of 2mM catecholic substrates by 1 microM LIP after 1h was in the following order: 4,5-DCC (95%)>4-CC(90%)>CAT(55%)>4-MC(43%). Except for 4-MC, all reactions were accompanied by the formation of insoluble products, leading to LIP precipitation. LIP was exposed to soluble or insoluble product-dependent inactivation, depending on the substrates tested, immediately at the start of the reactions. Despite immediate enzyme inactivation, removal of catecholic substrates continued, resulting in oligomeric product formation. Major oxidation products analyzed were compatible with dimeric, trimeric and tetrameric structures. Ether linkages and a benzoquinone structure were detected in two purified oligochlorocatechols. Catechol derivatives removal initiated by LIP, seems to be different for each catecholic substrate in terms of substrate consumption and transformation, and of enzyme activity.
