Abstract
Background: The application of skull pin holder elicits an adverse hemodynamic response that can be deleterious; there are many drugs that have been used to attenuate this response. We have conducted this study to evaluate the efficacy of intravenous (i.v.) dexmedetomidine on attenuation of hemodynamic responses to skull pin head holder application and to compare the effectiveness of two doses of i.v. dexmedetomidine (1 μg/kg and 0.5 μg/kg bolus). Materials and Methods: Ninety American Society of Anesthesiologists physical Status I–III patients undergoing craniotomy were randomized into three groups of thirty each. After intubation, patients in Group A received 1 μg/kg of i.v. dexmedetomidine, Group B received 0.5 μg/kg of i.v. dexmedetomidine, whereas Group C received an equivalent quantity of normal saline. Hemodynamic parameters were monitored regularly after skull pin insertion. Results: There was no significant difference in the monitored hemodynamic parameters among the three groups from baseline until intubation. Heart rate (HR) and mean arterial pressure (MAP) increased significantly at skull pin insertion and subsequent points in Group C, whereas the values decreased in Groups A and B (P < 0.05). Patients in Group A showed a higher and sustained attenuation of MAP. Patients in Group C had a higher incidence of tachycardia and hypertension requiring additional measures to attenuate the response. Conclusions: Dexmedetomidine in either dosage (1 μg/kg or 0.5 μg/kg) was effective in attenuating hemodynamic response to skull pin insertion. Dexmedetomidine in doses of 0.5 μg/kg was as effective in attenuating the HR and MAP response to skull pin insertion as compared to a dose of 1 μg/kg.

Abstract
Background: The application of skull pins in neurosurgical procedures is a highly noxious stimulus that causes hemodynamic changes and a rise in spectral entropy levels. We designed a study to compare intravenous (IV) labetalol and bupivacaine scalp block in blunting these changes. Patients and Methods: Sixty-six patients undergoing elective neurosurgical procedures were randomized into two groups, L (labetalol) and B (bupivacaine) of 33 each. After a standard induction sequence using fentanyl, propofol and vecuronium, patients were intubated. Baseline hemodynamic parameters and entropy levels were noted. Five minutes before, application of the pins, group L patients received IV labetalol 0.25 mg/kg and group B patients received scalp block with 30 ml of 0.25% bupivacaine. Following application of the pins, heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), and response entropy (RE)/state entropy (SE) were noted at regular time points up to 5 min. Results: The two groups were comparable with respect to their demographic characteristics. Baseline hemodynamic parameters and entropy levels were also similar. After pinning, the HR, SAP, DAP, MAP, and RE/SE all increased in both groups but were lower in the scalp block group patients. HR increased by 19.8% in group L and by 11% in group B. SAP increased by 11.9% in group L and remained unchanged in group B. DAP increased by 19.7% in group L and by 9.9% in group B, MAP increased by 15.6% in group L and 5% in group B (P < 0.05). No adverse effects were noted. Conclusion: Scalp block with bupivacaine is more effective than IV labetalol in attenuating the rise in hemodynamic parameters and entropy changes following skull pin application.

Abstract
Introduction Le maintien de la stabilité hémodynamique est un objectif primordial de l'anesthésie pour craniotomie. Peu d’études ont prouvé l'efficacité de l'infiltration du scalp par un anesthésique local pour le maintien de la stabilité hémodynamique après l'incision. L'objectif de notre travail est d’évaluer l'influence de l'infiltration de la ligne d'incision du scalp par la lidocaïne à 0,5% adrénalinée sur les paramètres hémodynamiques après incision pour craniotomie supratentorielle. Méthodes Étude prospective en double aveugle réalisée au bloc opératoire de l'hôpital des spécialités de Rabat sur une période d'une année incluant 80 malades programmés pour craniotomie supratentorielle. Les malades étaient randomisés par tirage au sort en 2 groupes: Le groupe 1 était infiltré par 40 ml du sérum salé adrénaliné (1/200 000) et le groupe 2 était infiltré par 40 ml de la lidocaïne 0,5% adrénalinée (1/200 000). Le critère de jugement principal était la pression artérielle moyenne (PAM) après l'incision. L’étude statistique a fait appel aux tests t de student et l'U- mann-whitney. Une valeur de p <0.05 était considérée significative. Résultats L’étude a inclus 80 patients (40 hommes et 40 femmes). L’âge moyen était 42,33±14,76 ans. Le poids moyen était 71,58 ±10 kg. Le 3/4 des patients était ASA 1, seulement 25% étaient ASA2. La durée moyenne de la chirurgie était de 252,06±38,62 mn. Les deux groupes étaient comparables concernant l’âge, le sexe, le poids, la durée d'intervention, le type d'abord chirurgical, la dose totale du fentanyl reçue jusqu'a l'incision, ainsi que les paramètres hémodynamiques avant l'incision. Après l'incision la FC moyenne a augmenté dans les deux groupes: 80,53±7,72 bpm dans le groupe contrôle et 76,85±8,52 bpm dans le groupe lidocaïne. La différence d'augmentation de la FC entre les deux groupes était statistiquement significative (p = 0,047). L'augmentation de la PAM était également significativement plus élevée dans le groupe placebo (96,45± 3,53mmHg vs 94,75± 3,76mmHg) (p = 0,041). Nous n'avons pas noté de troubles de rythme ou d'hypertension artérielle par les solutions adrénalinées à 1/200000. Par contre, six cas d'hypotension artérielle ont été notés (3cas dans chaque groupe) après 2 minutes de l'infiltration et ayant répandu au remplissage par 500 ml de sérum salé 0,9%. Conclusion L'infiltration par la lidocaïne procure une stabilité hémodynamique (PAM et FC) statistiquement significative. Les autres études rapportées dans la littérature et avec un échantillon réduit ont permis de retrouver une différence significative concernant uniquement la PAM et non la fréquence cardiaque.

Abstract
OBJECTIVE In this double-blind prospective clinical study, we investigated the effects of fentanyl and dexmedetomidine as adjuvant agents in supratentorial craniotomies on the following: hemodynamic changes during perioperative and recovery periods, brain edema perioperatively, recovery times and side effects, such as hypertension, shivering, nausea and vomiting. MATERIALS AND METHODS Thirty consenting ASA physical status I-II patients undergoing intracranial tumor surgery were randomly divided in two groups. In group D (n=15), dexmedetomidine was infused as a 1 μg/kg bolus dose 10 minutes before induction of anesthesia and maintained with 0.4-0.5 μg/kg/min during the operation. In group F (n=15), animals were given fentanyl 0.02 μg/kg/min as an infusion for anesthesia maintenance. At induction, fentanyl was given as a 2 μg/kg dose in group D and as a 4 μg/kg dose in group F. Hemodynamic changes, recovery times and postoperative side effects were recorded before induction, during the perioperative period and 24 hours postoperatively. RESULTS In group D; MAP and HR values after intubation, after skull clamp insertion and after extubation were lower than in group F (p<0.05). In group D, cerebral relaxation scores were also significantly lower. Recovery times were found to be shorter in group D as compared to group F; the same trend was observed for the supplemental opioid requirement. During the postoperative period, there was no shivering, nausea or vomiting in group D, but in group F, 3 patients complained of shivering, and 2 patients experienced nausea and vomiting. CONCLUSION In our study, we found that dexmedetomidine controlled the hemodynamic changes better than fentanyl perioperatively, after extubation and during the early postoperative period. Our results suggest that that dexmedetomidine is safer and more effective in controlling hemodynamic changes during surgical stimulation than the standard agents used in neuroanesthesia.

Abstract
BACKGROUND Use of Mayfield clamps is associated with potentially hazardous hemodynamic effects. Use of local anesthetic infiltration has yielded varying results in blunting of this response. The authors' objective was to study the effect of lidocaine with adrenaline infiltration at Mayfield pin sites on hemodynamic response in comparison with no intervention. METHODS This was a prospective cohort study conducted at a tertiary care center from January 2012 to July 2012. Patents undergoing elective craniotomies over the study period were included and divided in two groups, Group A received lidocaine infiltration of the pin sites prior to insertion, while Group B did not. Hemodynamic response to pin application was then studied at various intervals. RESULTS A total of 30 patients were enrolled in each group. The baseline mean arterial pressure (MAP) and heart rate prior to pin placement in Groups A and B were comparable (P = 0.985 and 0.313). The MAP at 60 seconds after application of skull pins was significantly different in the two groups; 86.13 (±9.73) mmHg versus 104.03 (±12.95) mmHg (P < 0.001). However, the MAP at 30 minutes after application of skull pins in both groups was comparable (P = 0.585). The mean heart rate measured at 60 seconds after skull pin insertion in Group A was 78.23 (±7.19)/min while in Group B, it was 103.07 (±6.98)/min, the difference being statistically significant (P < 0.001). CONCLUSION Hemodynamic changes due to the application of Mayfield clamps during elective craniotomies can be effectively prevented by prior lidocaine with adrenaline infiltration of the pin insertion sites.

Abstract
OBJECTIVE The aim of this study was to investigate the oxidative, hemodynamic, and analgesic effects of local lidocaine infiltration, or intravenous (IV) fentanyl injection, or a combination of lidocaine and IV fentanyl during head fixation in a 3-pin headrest in patients undergoing elective craniotomy. DESIGN Double-blind, randomized, placebo-controlled study. SETTING Gaziantep University Medical Faculty, Department of Anesthesiology and Reanimation. METHODS Eighty patients were randomly assigned to one of four groups. Five minutes before pin fixation, patients in group L received 1 mg/kg of lidocaine 2% for scalp infiltration (n=20), group F received 1 μg/kg of IV fentanyl (n=20), group FL received 1 mg/kg of lidocaine 2% and 1 μg/kg of fentanyl (n=20), and group P received a placebo (n=20). Following standard anesthesia, basal, pre- and post-fixational hemodynamic data were recorded. Blood samples were taken for evaluation of oxidant and antioxidant levels before and after pin fixation. RESULTS The total antioxidant levels after pin fixation were highest in group FL followed by group F, then group L and finally group P (ie, FL>F>L>P) (P<0.05). The mean arterial blood pressure (MAP) after pin fixation was higher than the MAP before pin fixation in groups L and P (P<0.05), but was lower in groups F and FL (P<0.05). CONCLUSION The combination of fentanyl and lidocaine before pin fixation is useful in preventing severe hemodynamic response to pain stimuli, such as pin fixation, and in increasing total antioxidant levels in the post-fixational period during craniotomy in adults.
