“…In addition, given that the TFL latency can be altered according to the tail and room temperature (Berge et al, 1988), all our experiments were performed in a temperature‐controlled environment (22 ± 2 °C), with high coil temperatures (up to 75 °C) and avoiding any visual or auditory cues, ensuring reliability. Highlighting that the descending inhibitory modulation becomes apparent between the 15th (Guy and Abbott, 1992; Weber et al, 1977) and the 21st (Van Praag and Frenk, 1991) postnatal days is crucial, which is a result of the delay in receptors maturation in the dorsal horn and the time‐dependent myelination of Aδ fibers (involved with thermal sensitivity) (Fitzgerald, 1991). According to the ontogeny of rats, the receptors reach maturity and Aδ fibers become myelinated, promoting faster conduction velocities and nociceptive response.…”

The present study aimed at investigating both the early and long‐term effects of maternal deprivation as well as gender on neuromotor reflexes, anxiety behavior and thermal nociceptive responses. A total of 64 Wistar rats pups (32 males, 32 females) were utilized and were deprived of their mother for 3 h/daily, from postnatal day 1 (P1) until P10. Successively, animals were divided into 2 groups: control group (C) ‐ pups no subjected to intervention; and the maternal‐deprived group (MD): pups subjected to maternal deprivation. The neuromotor reflexes were evaluated through the righting reflex and negative geotaxis tests; the exploratory behavior by open field test (OFT); the anxiety‐like behavior by elevated plus‐maze test (EPM); the thermal nociceptive responses byhot plate (HP) and tail‐flick (TFL) tests. All the animals subjected to maternal deprivation showed a delayed reflex response at P8 in the negative geotaxis test. In contrast, the OFT at P20 identified an effect of gender on the outer crossings and grooming as well as an interaction between gender and maternal deprivation on latency. Additionally, effect of maternal deprivation in the open and closed arms as well as gender effect in the protected head‐dipping (PHD) and non‐protected head‐dipping (NPHD) were observed at P20 (EPM). In contrast, there were a gender effect on latency and an interaction between gender and maternal deprivation on rearing at P42. Moreover, in nociceptive tests was observed an analgesic effect induced by maternal deprivation; however, in the TFL test, only deprived females showed this effect. Surprisingly, only control animals presented an ontogeny nociceptive effect in the HP testat P21 and P43, which may be related to an increase in the inhibitory nociceptive pathways throughout life. In this way, we suggest maternal deprivation to be able to anticipate the maturation of the inhibitory nociceptive pathway. In conclusion, maternal deprivation induced a delayed reflex response at P8 and altered the anxiety and nociceptive behaviors according to the time after exposure to this stressor, in a gender‐specific manner.

“…The anaesthetic management of patients with Eisenmenger's syndrome or carotid body tumour resection are each associated with significant anaesthetic problems, which have been previously described [3–16]. Their coexistence represents a rare and potentially greater anaesthetic challenge, with only a single case report identified in which general anaesthesia was used [17].…”
