ABSTRACT

BACKGROUND: Perioperative cognitive dysfunction (PCD) is a very prevalent clinical syndrome due to the progressive aging of the surgical population.The aim of our study is to evaluate the clinical practice of Spanish anesthesiologists surveyed regarding this entity. MATERIAL AND METHODS: Prospective online survey conducted by the Neurosciences Section and distributed by SEDAR. RESULTS: 544 responses were obtained, with a participation rate of 17%. 54.4% of respondents never make a preoperative assessment of cognitive impairment, only 7.5% always do it. 79.6% lack an intraoperative management protocol for the patient at risk of PCD. In the anesthetic planning, only 23.3% of the patients was kept in mind. Eighty-nine percent considered regional anesthesia with or without sedation preferable to general anesthesia for the prevention of PCD. 88.8% considered benzodiazepines to present a high risk of PCD. 71.7% considered that anesthetic depth monitoring could prevent postoperative cognitive deficit. Routine evaluation of postoperative delirium is low, only 14%. More than 80% recognize that PCD is underdiagnosed. CONCLUSIONS: Among Spanish anesthesiologists surveyed, PCD is still a little known and underappreciated entity. It is necessary to raise awareness of the need to detect risk factors for PCD, as well as postoperative assessment and diagnosis. Therefore, the development of guidelines and protocols and the implementation of continuing education programs in which anesthesiologists should be key members of multidisciplinary teams in charge of perioperative care are suggested.

ABSTRACT

We present the case of an adult patient with drug-resistant epilepsy caused by extensive inflammation in the right cerebral hemisphere. She was scheduled to undergo right functional hemispherectomy, which is common in pediatric surgery, but about which few studies have been published with respect to adult patients. During the intraoperative period, the density spectral array of the bilateral bispectral index (BIS) VISTATM monitoring system was used. We observed a power increase in low frequency (0.1-4Hz) and alpha bands (8-12Hz) in the right hemisphere, where the epileptogenic focus was. During disconnection from the frontal lobe, there was a marked decrease of power in low frequency and alpha bands on the right side, with no changes during disconnection from other areas of the brain. We think that further studies are needed to determine whether the density spectral array can be a useful tool for monitoring the effectiveness of functional hemispherectomy.

ABSTRACT

Epilepsy surgery is a well-established treatment for patients with drug-resistant epilepsy. The success of surgery depends on precise presurgical localisation of the epileptogenic zone. There are different techniques to determine its location and extension. Despite the improvements in non-invasive diagnostic tests, in patients for whom these tests are inconclusive, invasive techniques such intraoperative electrocorticography will be needed. Intraoperative electrocorticography is used to guide surgical resection of the epileptogenic lesion and to verify that the resection has been completed. However, it can be affected by some of the anaesthetic drugs used by the anaesthesiologist. Our objective with this case is to review which drugs can be used in epilepsy surgery with intraoperative electrocorticography.

ABSTRACT

We report the case of an aborted awake craniotomy for a left frontotemporoinsular glioma due to ammonia encephalopathy on a patient taking Levetiracetam, valproic acid and clobazam. This awake mapping surgery was scheduled as a second-stage procedure following partial resection eight days earlier under general anesthesia. We planned to perform the surgery with local anesthesia and sedation with remifentanil and propofol. After removal of the bone flap all sedation was stopped and we noticed slow mentation and excessive drowsiness prompting us to stop and control the airway and proceed with general anesthesia. There were no post-operative complications but the patient continued to exhibit bradypsychia and hand tremor. His ammonia level was found to be elevated and was treated with an infusion of l-carnitine after discontinuation of the valproic acid with vast improvement. Ammonia encephalopathy should be considered in patients treated with valproic acid and mental status changes who require an awake craniotomy with patient collaboration.

ABSTRACT

BACKGROUND AND OBJECTIVE: Neuromuscular blockers (NMBs) have traditionally been thought to increase the risk of respiratory complications, although drawing conclusions in this respect would require complex studies in large patient samples. The aim of this study was to analyze data from the ARISCAT study to obtain an overall picture of how NMBs are being used and blocks are reversed in Catalonia, Spain. MATERIAL AND METHODS: NMB use as reflected in data from the ARISCAT study was analyzed. Case information from the database was organized into 4 groups: for patients not receiving a NMB (No-NMB), patients whose NMB block was performed with succinylcholine alone (SC), patients who received a single dose of a nondepolarizing NMB (SD-NMB), and patients who received additional doses of a nondepolarizing NMB or a continuous perfusion (AD-NMB). We analyzed patient characteristics, clinical and surgical characteristics, and complications during and after surgery in each of the groups. Variables were also analyzed according to whether the NMB effect had to be reversed. RESULTS: Of the 2991 patients included in the ARISCAT study, 1545 received general or combined anesthesia. Of the 1545 patients, 1267 (89%) received a NMB and the block was reversed with an anticholinesterase agent in 54%. The group distribution was as follows: No-NMB, 103 patients; SC, 31; SD-NMB, 527; and AD-NMB, 709. The highest rate of comorbidity, longest duration of surgery, highest rate of complications during and after surgery, and the longest hospital stays were observed in the last of the 4 groups (AD-NMB). Reversion was required significantly more often after cardiothoracic and upper abdominal surgical procedures; the complication rates after those 2 types of surgery were statistically similar. CONCLUSIONS: Nondepolarizing NMBs are used in combination with general anesthesia often in Catalonia; their use is associated with duration and type of surgery. A reversal drug is administered relatively more often in Catalonia than in other geographic areas.
