Abstract
SummaryPropofol is a intravenous anaesthetic most commonly used in ultrasound oocyte retrieval. We studied if the use of propofol had an effect on mouse oocyte maturation, pregnancy, childbirth and progeny and investigated the correlation between propofol side effects and reproductive performance in mice. There was no statistical difference in mating, pregnancy, childbirth, litter size, the number of stillbirths and survival between each group (P>0.05). Propofol also had no effect on polar body extrusion in oocyte maturation as well as on pronucleus formation and, subsequently, early embryo development (P>0.05). An increased concentration of propofol had no effect on this result, although propofol at more than 0.01 mg/ml reduced polar body extrusion. Different concentrations of propofol had no effect on oocyte culture in vitro, pronucleus formation and early embryo development.

Abstract
The main goal of the present retrospective study is to compare four analgesic methodologies (EMLA cream, propofol, thiopental sodium, sevoflurane) for in vitro fertilization (IVF) oocyte retrieval. We found that most anaesthetic parameters were not significantly different among all treatments. In contrast, significant differences were revealed in all groups for total number of oocytes retrieved per patient, rate of mature oocytes at metaphase II stage (MII) and percentage of fertilization and embryo development. In the EMLA cream and thiopental sodium groups we observed the highest percentage of MII oocytes (P < 0.001). Fertilization rate in the EMLA and sevoflurane groups were similar but significantly higher than the propofol and thiopental sodium groups (P < 0.001). The highest rate of anomalous fertilization was observed in the propofol group. Rate of embryo development was similar in all groups but sevoflurane group had a lower percentage of good embryos. In conclusion, by comparing different anaesthetic techniques with different mechanisms of action and administration, potential negative effects of these drugs on the initial stages of human IVF procedure were revealed. Therefore, a local anaesthetic cream is proposed as an acceptable alternative option for anaesthesia during transvaginal oocyte retrieval.

Abstract
Propofol, which is widely used as an intravenous anesthetic, has a phenolic structure similar to that of α-tocopherol with antioxidant properties that could prevent genotoxicity and cytotoxicity in lymphocytes of anesthetized patients. The aims of this study were to evaluate oxidative DNA damage and apoptosis in lymphocytes and the expression of DNA repair genes in blood cells from patients undergoing elective surgery under anesthesia with propofol. Twenty healthy adults of both genders (18-50 years old) who were scheduled for otorhinological surgery were enrolled in this study. Blood samples were collected before anesthesia induction (T₁-baseline), 120 min after anesthesia induction (T₂), and on the first postoperative day (T₃). Oxidative DNA damage in peripheral lymphocytes was assessed using the comet assay. Lymphocytes were phenotyped as T helper or cytotoxic T cells, and apoptosis was evaluated using flow cytometry. The expression of DNA repair genes (hOGG1 and XRCC1) was assessed by quantitative polymerase chain reaction. A reduction in the level of oxidized purines in DNA (P < 0.01) was observed 120 min after anesthesia induction, and reduced apoptosis of T helper cells was observed 120 min after anesthesia induction and on the first postoperative day. Down-regulation of hOGG1 and XRCC1 gene expression was observed on the first postoperative day. In conclusion, patients undergoing non-invasive surgery under propofol anesthesia presented lower levels of oxidized purines and apoptosis of T helper lymphocytes. Furthermore, anesthesia with propofol did not directly influence the expression of the DNA repair genes hOGG1 and XRCC1 in blood cells.

Abstract
Recent studies have demonstrated the genotoxicity of anesthetics in patients who have undergone surgery and in personnel who are occupationally exposed to anesthetics. However, these findings are controversial. Herein, we used the comet assay (single-cell gel electrophoresis) to investigate the genotoxic effects of two volatile compounds [isoflurane (ISF) and sevoflurane (SVF)] that are used in inhalation anesthesia, and of one intravenous (iv) anesthetic compound [propofol (PF)]. The groups consisted of 45 patients who underwent minimally invasive surgery that lasted at least 2h. Patients were classified as physical status I using the criteria of the American Society of Anesthesiologists (ASA) and were randomly allocated to receive ISF, SVF or PF anesthesia. Venous blood samples were collected at three time points as follows: before the premedication and the induction of anesthesia (T(0)); 2h after the beginning of anesthesia (T(1)); and on the day following surgery (T(2)). DNA damage (strand breaks and alkali-labile sites) was evaluated in peripheral blood lymphocytes. For each patient, one hundred nucleoids were analyzed per time point using a semi-automated image system. Patients did not differ with respect to their demographic characteristics, the duration of surgery, or the total doses of intraoperative drugs. The amount of DNA damage was not different among the three groups before anesthesia (T(0)). No statistically significant (p>0.05) increase in DNA damage was detected during (T(1)) or after anesthesia (T(2)) using three different protocols (ISF, SVF or PF). In conclusion, general anesthesia with inhaled ISF and SVF or iv PF did not induce DNA strand breaks or alkali-labile sites in peripheral lymphocytes. Therefore, our results show that the genotoxic risk of these anesthetics, for healthy patients undergoing minimally invasive otorhinological surgery, is low or even absent.

Abstract
Context: Analgesia is based on balanced anaesthesia, which is usually maintained by administration of narcotic agents. In some patients, it is not possible to use narcotics. We compared hemodynamic changes, anaesthesia depth, emetic sequelae and post-operative pain between sodium Diclofenac, Ketamine-Propofol (DKP) and Fentanyl-Midazolam (FM). Aims: The effectiveness of an anaesthetic technique employing sodium was compared against in patients undergoing elective surgery. Settings and Design: In a clinical trial study, 82 patients who attended for an elective surgery were randomly divided into two groups. Materials and Methods: In DKP group pre-medication included Sodium Diclofenac 1 mg/kg and Midazolam 0.02 mg/kg, whereas, in FM group they were Fentanyl 2 μg/kg and Midazolam 0.02 mg/ kg. Anaesthesia induction in both groups was the same. Anaesthesia was conserved in DKP group by using Propofol plus Ketamine infusion plus N2O 50% and in FM group with Fentanyl plus Midazolam plus N2O 50%. Hemodynamic changes, depth of anaesthesia, nausea and vomiting, post operative analgesic effects were recorded. Results: Hemodynamic changes and depth of anaesthesia were similar throughout the maintenance phase in two groups. In FM group, significant increase in heart rate was recorded in recovery room. Pain score according to visual analogue scale (VAS) and need for analgesics, was significantly more in FM group compared to DKP group (P = 0.000). No patient suffered from nausea, vomiting or hallucinations. Conclusions: This study revealed that intravenous administration of Sodium Diclofenac along with Ketamine and Propofolplus N2O 50% for general anaesthesia provides a balanced anaesthesia as well as hemodynamic stability, and adequate depth of anaesthesia. It also reduces the postoperative pain and need for narcotics. We recommended DKP plus N2O 50% method for patients prohibited from opioid administration. It will be an acceptable method in sensitive patients.

Abstract
INTRODUCTION Exposure to anesthetics in the health environment may entail a health risk for patients and operating room personnel. Knowing the effects of anesthetic agents on genetic material could be a valuable basic support for anesthesia care providers to improve treatment performance, increase patient safety and reduce the risks for patients and staff in the operating room. AREAS COVERED Relevant literature was identified using MEDLINE, CINAHL® and Cochrane Library databases. Over 200 abstracts for articles published from 1980 to 2010 were examined. Original articles were reviewed and relevant citations from these articles were also considered. EXPERT OPINION Despite some conflicting results, the current available data indicate that exposure to anesthetics, especially nitrous oxide and halogenated agents, is associated with general and genotoxic risks, whereas intravenous agents, such as propofol and its metabolites are not associated with genotoxic effects. Moreover, given that different anesthetic drugs are used in combination it is, thus, very difficult to understand whether the observed effects or absence of effects are due to an individual agent action or linked to a synergy action of different anesthetics involved. Further clinical and experimental evidence is warranted.

Abstract
BACKGROUND AND OBJECTIVES Inhaled anaesthetics have been studied regarding their genotoxic and mutagenic potential in vivo. Propofol differs from volatile anaesthetics because it does not show mutagenic effects and it has been reported to be an antioxidant. However, there are no studies with propofol and genotoxicity in vivo. The study aimed to evaluate the hypothesis that propofol is not genotoxic and it inhibits lipid peroxidation [malondialdehyde (MDA)] in patients undergoing propofol anaesthesia. METHODS ASA physical status I patients scheduled for elective surgery, lasting at least 90 min, were enrolled in this study. Initially, the estimated plasma concentration of propofol was targeted at 4 microg ml(-1) and then maintained at 2-4 microg ml(-1) until the end of surgery. Haemodynamic data were determined at baseline (before premedication) and in conjunction with target-controlled infusion of propofol: after tracheal intubation, 30, 60 and 90 min after anaesthesia induction and at the end of the surgery. Venous blood samples were collected at baseline, after tracheal intubation, at the end of the surgery and on the postoperative first day for evaluating DNA damage in white blood cells (WBCs), by comet assay, and MDA levels. RESULTS Haemodynamic data did not differ among times. No statistically significant differences were observed for the levels of DNA damage in WBCs, nor in plasma MDA, among the four times. CONCLUSION Propofol does not induce DNA damage in WBCs and does not alter MDA in plasma of patients.

Abstract
BACKGROUND Ultrasonically guided transvaginal oocyte retrieval is a relatively short procedure that is performed on an outpatient basis. Any anaesthetic technique may interfere with certain aspects of human oocyte fertilisation or embryo implantation. The optimal anaesthetic technique should allow good surgical anaesthesia with minimal side effects, a short recovery time and high rate of successful pregnancy. METHOD We present our experience and evaluation of the various techniques studied to carry out this technique. RESULTS AND CONCLUSION Amongst the various available total intravenous anaesthesia options, propofol/ remifentanil or fentanyl technique of sedation appears to be safe and effective.

Abstract
PURPOSE OF REVIEW To review the most recent literature on anesthesia for in-vitro fertilization. RECENT FINDINGS Very limited new information has become available in the review period. Propofol seems to be an acceptable option for anesthesia/sedation during in-vitro fertilization but more research is necessary to definitively establish its safety. Remifentanil is also an effective alternative. SUMMARY Presently, propofol and remifentanil seem to be acceptable options for anesthesia for in-vitro fertilization but further research is required.

Abstract
Diazepam is a benzodiazepine with anticonvulsant, anxiolytic, sedative and muscle-relaxing properties. Many aspects of its toxicity have been investigated, including genotoxic and carcinogenic effects in various model systems. However, it is still unclear whether diazepam is in fact a genotoxic agent. Propofol is a rapid-onset, short-acting intravenous anesthetic agent. It is used widely for the induction and maintenance of anesthesia as well as for long-term sedation in intensive care units. There is limited information in the literature on its genotoxic effects. Both drugs are commonly used as anesthetic in patients undergoing open-heart surgery. Therefore, we investigated the possible genotoxic effects of propofol and diazepam in those patients, using a chromosomal aberration (CA) assay. Peripheral blood samples were collected from 45 patients before induction of anesthesia and at the end of the anesthesia with diazepam or propofol. In Group I (n=24), anesthesia was induced with 0.2 mg kg(-1) diazepam and 10 microg kg(-1) fentanyl. In Group II (n=21), anesthesia was induced with 1 mg kg(-1) propofol and 10 microg kg(-1) fentanyl. Pancuronium bromide (0.1 mg kg(-1)) was administered for skeletal muscle relaxation in both groups. Anesthesia was maintained by diazepam administration at 5 mg kg(-1) in Group I or by continuous propofol administration at 2-4 mg (kg h)(-1) in Group II. All patients received 0.02 mg kg(-1) pancuronium and 5 microg kg(-1) fentanyl boluses at 30-40 min intervals for anesthesia maintenance. Body temperature was controlled during bypass in the two groups. We found that the mean frequency of CAs in both groups before and at the end of the anesthesia were not statistically significantly different. Our analysis also indicated that age, smoking habit and gender were not confounding factors. In conclusion, our results indicate that diazepam and propofol do not exert genotoxic effects in blood cells during open-heart surgery.

Abstract
BACKGROUND Propofol is frequently used for general anesthesia in children although little is known about possible genotoxic effects in humans. We investigated the formation of sister chromatid exchanges (SCE) in metaphase chromosomes of T-lymphocytes of children as a marker for possible genotoxocity following total intravenous anesthesia with propofol for minor surgical procedures. METHODS 40 children ASA classification I-III were included (ASA I n=34, ASA II n=5, ASA III n=1) in the study. Anesthesia was induced by propofol (3mg/kg) and alfentanil. Succinylcholine or rocuronium were administered for muscle relaxation. After tracheal intubation anesthesia was maintained by continuous propofol infusion at 12 mg/(kgh). Blood samples were drawn before induction and after termination of anesthesia. Following a 72 h cell culture period, 25 T-lymphocyte metaphases per blood sample for all children were analyzed for SCE frequencies. RESULTS Total intravenous anesthesia with propofol on children did not influence SCE rates in metaphase chromosomes of T-lymphocytes. No SCE differences could be detected between blood samples before initiation and after termination of anesthesia (Wilcoxon signed rank test). Slightly elevated SCE rates were obtained in T-lymphocytes of girls compared to boys, but these differences did not reach statistical significance. CONCLUSIONS Propofol anesthesia under the chosen conditions did not induce the formation of SCE in children in vivo. No genotoxic effect of a short term exposure to propofol during pediatric anesthesia had been observed.
